I believe taigh has a 250.
We have a Howard Super Ventura. If I am not mistaken the 250's were manufactured from the Loadstar airframes and uses Pratt & Whitney R-1830's.
Ours is still registered as a Lockheed PV-1 but with Howard modifications making it a Super Ventura. Originally it had P&W R-2800-31's at 2000 HP (just like our PV-2) but one of the many mods to the aircraft was adding R-2800 CB-16's that put out 2500 HP. There are many other mods too.
The cool thing for me is that the PV-1 and PV-2 type ratings are all on the same ticket namely the Lockheed B-34 type rating.
Here is a web page about our Super Ventura:

Here is a shot that is pretty old

I think that the Super Ventura was the ultimate aircraft in the Lockheed/Howard series and from what I have heard the Super Ventura was the fastest in the fleet. It had all of the bells and whistles that the 500 did (ADI, auto feather, anti lock brakes, speed brakes etc) except it was not pressurized. The purpose built fuselages had lots of extra structure inside, about twice the number of bulkheads and stringers, so it was a lot heavier. 
Some day I would like to race one of Tony Phillippi's Howard 500's to find out. Anyone have a spare gas card I could use?
