interesting to see that you guys restored Dr Joe's P-51 here in Lexington KY. I always wondered where it came from.

Actually it was already restored when Dr. Joe bought it. I was helping with the Annual Inspection on Honey for Dr. Joe. I think she was restored by Brad Hood. I been helping restore Dr. Joe's Ryan PT-22. Great collection of Warbirds they have.

Here are some up dated pictures of the seat progress. All of the aluminum parts are finished and ready from primer, still have to make a couple of the small steel parts.

Do you have the NAA Document that is a cross reference between the NA-64, NA-66, and the T-6? It lists which parts are in common etc.

If you don't have it I will try to can it into a PDF for you. Probably won't happen until after our auction, though...

Update: October 24, 09

Acquired all the left over parts from the restoration of Yale 3400, Got the lower wing attach angle cover bands i was missing, plus the much need prop hub. I have a bunch of parts that i will not be using but selling to help fund the restoration.

Received parts of shoulder seat harness release, donated by Eric Miller, Project Warbird Museum.

Placed an order for more 4130 steel for the seat parts that need to be made. Currently in the process of repairing the damage to the pilot seat. There are two cracks near the upper seat support, I designed two repair patches in CAD that will be riveted on both sides of the seat over the crack. I have also made the new support seat pan that was severely corroded and am in the process of fitting it into place.

Do have who the company that manufacture the seats was for this aircraft? (Slick Johnson?)

Does the seat use a bungee cord as part of the suspension?

I been try to tract down the history on these “squareback” seats

I think they get there starts in the need to accommodate the French backpack parachutes

The typical prewar US aircraft seat was a round back bucket for a seat pack parachutes only

When all the French order to US that was a need for a modified seat to fit the French backpack parachutes

I been also trying to show the same seat being used in the Tomahawk

Hello, I have been told the seat that are used in the NA-64 were manufactured by American Seating company out of Grand Rapids MI. The Slick Johnson seats are used in the AT-6 Texan and are different then the type I have. These seats do use a bungee cord as part of the suspension to assist in the seat adjustment like the T-6.

The Assembly # on the seat is 49-53074... the 49- Prefix stands for Harvard 1 Modified BC-1 England 2 place trainer.

From what I understand, the seats are not comfortable with US parachutes.

Spent today rearranging the shop and tools, I bought my self a label maker so had some fun with that labeling the tools chest. I did manage to get a couple of parts made for the seats and plan on doing more tomorrow.
