I have 49 no dash, that left the factory in January of 1983.
I've had it for sale locally for some time and received an Email
this morning from a prospective buyer who lives in California
wanting to know if was still for sale. I told him yes, but be sure
to check and see if the revolver was legal in Calif.

He replied that he had checked with his local FFL and was told
he found a 37 and a 38 model but no 49. Was advised to contact
the seller and obtain a SKU number which would make it real
easy to look it up.

I get the impression the prospective buyer is a novice gun
buyer.

My question is how do I find a SKU number and were they
even in use in 1983?

Bought the revolver with no box or docs.
Any help much appreciated,

Regards
Dick
