If by "P337" you are in fact looking for a Pressurized 337, then I have one available.
It is a 1975 T337G pressurized Skymaster. Approximately 3000 TTAF, FE 1550 SMOH, RE 1460 SFRM and Props at 160 SNEW and SPOH. Engines at present are running well with oil consumption at 10-15 hours /litre.
Tan Leather Interior was new in 2009 and the only seat that has been used regularly is the Pilot's seat. Notable improvements include Riley Air Conditioning and Intercoolers.
This would be an ideal platform for overhauled engines and while the electronics are good and solid, the discerning owner might want to upgrade the GPS and add a custom paint job.
He or she would then have a plane that would outrun anything in its class.
If interested, I can provide additional information. You are most welcome to email me at
