Interesting tubing connected to 3 fittings on the exhaust on the inboard nacelle. Is that some kind of mixture monitor, or for pressurizing something?
I've made similar systems but they were for injecting smoke oil. I don't think the bombers wanted to show their position so I'm counting that one out.

I'm a bit confused...apparently the 91st reassigned DF A code after the Belle went home?

I set my GPS up to use the British/English voice rather than the American/English. Makes me feel like I'm James Bond when I drive around!

I wonder if B-17s had turbine inlet temperature gauges? Kind of looks like some kind of EGT setup to me.

Reusing codes was SOP. 1000s of a/c and only 26 letters in the alphabet :shock:

Quote:

This olive drab B17F is believed to have been the replacement for Memphis Belle, after that Fortress was sent back to the States on a War Bond Drive having starred in the famous wartime movie. Lady Luck served with the 91BG for eleven months before being transferred to Air Force Service Command (AFSC) as part of a reorganisation plan.

The plane flew its first combat mission on 28th June1943 to St Nazaire (flak city) with Capt Richard Weitzenfeld in command. Lt Fred Peterman's crew were assigned to the ship and completed twelve missions in it, including group leads. On 32rd September 1943, the squadron record notes: "Lt Vickery (bombardier) did a remarkably fine job of bombing." In addition to its yellow scripted titling on both sides of the nose, Peterman had the nickname of his wife "Toots" painted below the cockpit window on the left side. Four swastikas were also added above the lengthening row of mission bombs to denote the fighter claims by various gunners on his and other crews.

I thought exhaust mixture indicator as some T-6s had something of the sort on the firewall connected to the exhaust. Only have seen pics in the maintenance manual. Never seen one up close.

That tube is for the glycol cabin heater. Exhaust gases would heat
the glycol, which was routed into an exchanger, and the air passed into
the fuselage through ducting.

This was totally inadequate at 25,000ft., and was later replaced with
shrouds over the exhaust pipe (a-la Shoo Shoo Shoo Baby at the USAFM)
on later B-17G models.

Just FYI, DF*A #42-29837 was assigned to Bassingbourn Jun 7 '43. Then it flew in Italy, returned to US and melted down at Searcy, Ark on Jul 27 '45 LADY LUCK

I happened to have a "Pilot Training Manual for the B-17",which was intended to be used by experienced operational pilots transitioning to the B-17 from other types.I copied a couple of pages that pertain to the glycol heater in the B-17F.DryMartini gave a description of this system in answer to 51fixer's question earlier in this thread.

You mean they didn't hang the Belle's codes from the rafters after she was retired? :lol:

There is a cylinder head temp probe that replaces one of the spark plug washers. Is that what you are referring to? I've never seen a probe actually in the exhaust pipe of a T-6.

Me to. But I'm a writer, rather than an engineer, so there's more of my iggorance to fill.

Thanks guys, that's what makes WIX great.
