As Paul_WNC said most likely there are no frame markings but you could still look for some stampings on the front frame rails.

I found lots of numbers on the front end.

Also some have been luck enough to get whole SN's and model info:

So at least look... esp on a small run model like yours... most likely sent off to a sub-contractor for modification.

I found a parts book for the AFKX-352:

The manuals that site puts out are very, very good. And for $10EUR its a great deal.

Hey pfarber,
Thanks for the link on the manuals. Ordered one for the AFKX and G506 today.
Thanks again,
Steven
