Ed:
Thanks, but for me it's more of having good source material or having read good sources. I think of myself coming 20 or 30 years late to the party. At any rate, I did take a gander at the pics and the only thing I can make out on the backside of the receiver is "Ma". What it is, I do not know. The other mark on the lower right-hand side is interesting to say the least. I'll have to agree w/ PeteM in having someone knowledgeable to check the dimensions like tube thickness and the like.
Kind Regards,
