Had a fun thing happen recently. I was flying with the Collings Foundation training in the B-24 and we stopped in Goodyear Airport or as it will always be known to me as Litchfield Park. Litchfield was the US Navy's aircraft storage yard and is where 062 and our 'new' PV-2 37524 were stored from 1945 until 1958 and 1952 respectively.

Here is a shot of 84060 in storage at Litchfield. 062 must have been nearby.

Image

I asked Rick Turner about photos of the Harpoons in storage there and he emailed some to me. Thanks Rick!!

He said that the 5 dark rows of aircraft toward the bottom were PV-2's.

Image

The two large hangars in the photo are still there and it was pretty straight forward to figure out where the PV yard was. A kind gentleman from the Airport Authority allowed me to walk over there.

Here is a closer shot showing the row of PV-2's. I walked to the area that I thought was close and took some photos. Not quite the right perspective but I think I found the correct mountain range.
Image

Looking around I could see bits and pieces of the tie downs and some aircraft parts too.

Here is a magneto or induction vibrator lead

Image

A stainless steel hose clamp that I will clean up and put on the harpoon so it can fly again

Image

Image

A desiccant plug that was used to keep moisture out of engines that are preserved.

Image

None of the above could be directly tied to the PV-2 but this next one was. I was giddy to find it.

Image

This is a part of the control box for the APA-16 set. This was used to input the bomb type, speed and altitude information for dropping bombs through the APS-3 radar.

Image

Image

This is from the control box at the radar station on the lower left in the photo

Image

Image

Image

Image

This set was used in other aircraft as well but since it was in the area where the Harpoons were stored, I am going with it's from a HARPOOOON!

Cool stuff as usual, Taigh!

I'll bet you could uncover some great artifacts there using a metal detector!

Very cool!! I would wager to say that "Hot Stuff" (37396) is among those Harpoons, since she was stored at Litchfield.

The gun nose project has been coming together slowly. We have been making lots of parts as time and funding permits but we are now starting to bring all of those parts very close together.

Part of the problem has been the lack of information on the 8 gun nose. There are a few drawings in the blueprints but they are far from complete. Maybe we just don't have the latest set of drawings or maybe they just never finished it since the whole project was shut down abruptly at the end of the war. Who knows.

One of the issues for the gun nose has been the mounts for the guns. This is basically what we had to start with:

Image

We were lucky enough to have the basic prints for the front mount and we replicated them right to the drawing. It was modeled in 3D then machined and it turned out great. We did this with lots of parts and were able to replicate the mountings pretty accurately.

Here is the 3D cad drawing in SolidWorks:

Image

And the part assembled on the replica gun with four other parts also made by 3D/CNC . This constitutes the quick release mount that allowed the gun to swivel in azimuth and elevation to harmonize the guns.

Image

Next was the rear structure for mounting the guns as most of it was removed long ago when she was converted to an air tanker. The rear mount structure was quite elusive as we had no images besides the one above from the illustrated parts manual. Since the D model Harpoon is also a bit rare. Only 35 were made, and the few survivors seem to have had the same parts removed. Thankfully the prototype D model still exists and so does a lot of its rear gun structure. The first D model is BuNo 37535 which is in the Erickson collection in Madras, Oregon painted with the nose art of Russell's Raiders. Jim Martinelli was kind enough to open up the nose and he took many great photos for us. THANK YOU Jim! We really appreciate it.

From the photos I was able to figure out what parts to make and how to replicate what was originally in our nose. I started by removing the lower nose for cleaning and prep.

There were panels riveted in place where the spent casing and links would eject from the bottom of the nose when the guns were fired. I drilled these panels off which revealed some of the original non specular sea blue paint from 1945. It kind of matches our paint.

Image
Image

Now it was time to give it a good initial cleaning. The steam cleaner removed a lot of stuff that had been hiding in the hard to reach places. Some of it looked like the Arizona soil from its days at Litchfield from 1945 to 1958.

Image

The cleaning took off some of the top layers of paint and revealed inspectors stamps and grease pencil notations from the factory.

Image

Image

Image

The next job was to fabricate the webs in between the stepped bulkheads and then added the channels for the aft gun mounts.

Image

Now the fun part. bring all of the parts together to see how the guns fit.

Image

Image

Image

Four of the eight guns in place and they look pretty good. I can't wait to see all eight in place, with ammo boxes and feed chutes and chargers and...

One amazingly cool find was the stainless steel ejection chutes that mount under the guns. A long time ago I was at Aero Trader and came across one. I wasn't sure if it was even the correct part because I had never actually seen one but it looked like it might work. I bought it on a hunch and it turned out that it was indeed the ejection chute for the left bank of guns. How cool as it has got to be one of the rarest parts to find, well all of this D model nose stuff is hard to find but this was certainly one of the bigger ones. Funny how you can get all giddy over a stupid piece of sheet metal but I flet like Snoopy doing that dance he does.

Now I had a part to try and replicate the mirror image to make a matching set. Making this was doable but since it was spot welded it would be a pain to do properly and certainly take a lot of time.

A short while ago I saw an ad for harpoon parts and in the lot was...guess what? The right side ejection chute! What are the odds? It could just as easily have been the same side. I couldn't believe the luck.

Here is a photo of the two chute assemblies. They will need a lot of straightening and fitting but they play a large part to make the nose more complete. Awesome!

Image

Next will be to finish fitting all of the gun mount structure, fitting the ejection chutes, cleaning and painting the nose and new parts and then final assembly. We still have to make the ammo boxes but I have been holding out to try and find them. Pushing my luck? Oh, heck yes, but stranger things have happened.

More to come, slow but sure.
