WEll it's a little convoluted, but I have a listing of a Sensenich drawing number 42K19593 that corresponds to Type Certificate 546.

TC 546 is also designated for 43K19181 and you'll find that listing here, which shows it was a military contract for the civilian model 90-LA 76. That exact model isn't specifically listed on this list, but that list does show a 90-LA model with a different pitch, using the Continental R-670 5 engine, the same as yours. The horsepower is correct for that as well. I presume that Gardner simply manufactured it under an agreement with Sensenich, who held the type certificate for it. That practice was not uncommon.

It is clearly stamped for a PT 17 Airplane, however, and the other data fits even though we don't have it listed. It would have been made under a 1942 military contract and used on the PT 17 (Boeing Stearman).

Question Value???

By the way how much is this worth-is this something I should be donating to a museum-selling, I love it, but we are so broke right now; I'm extremely conflicted as to rather or not I should hang on to it. Also is there any way to track what plane(s) it was on?

It's almost impossible to know what specific plane it went on, and I think you'll be disappointed with a museum's response to donating it to them. It's not particularly rare.

The "market" for selling any collectible right now isn't very good. My advice is to just hang on to it. If you want to sell it, eBay is still your best bet. You'll need good photographs and a good description. I'd put a reserve on it. Use whatever value you want, but if it's higher than around $750 you might discourage any bidding.

It's 90 inches long. The drawing number (90 LA - 76) shows that the diameter, or length, is 90 inches and the pitch is 76 inches. It doesn't hurt to have the owner actually measure it as well, though, because if it's less than that it means the tips have been cut down.
