Looks like a '42 chassis based on the Panhard bar and the one body mount in the picture.
The chassis number matches '42 on Van Pelt's chart.
Can't help with any idea of the value of the 6 banger & trans; but I believe you would have a very limited market.
If the engine is free, get it running and put it on Market Place.
One of the flathead 6's is more sought after than the other. I can't remember if it is the G or the H engine that people want. I had one of each. One sold quickly. The other I scrapped.
I can vouch for the somewhat limited parts availability for the G-Series. I am in the process of restoring one now….parts are still out there, but you have to know where to look.There is limited part support for the G engine. The H is only slightly better with repop items.
I bought this rolling chassis from a gentleman in Indy, he swore it was a '42, I'm convinced, thought the vin (IGA-89779) that its a '41. But Henry being Henry, at that time it could be a '42.
Is there any value in the engine and trans?
Distributor is special. Many WW2 military vehicles used the G eng. It was preferred by the US Government. Try the site 503.com - all military. Newc
