Standard Products (SJ) stock restoration

[painter777]

When looking for one, that's a hard stock to find. I've found and own a number of S-HB stocks, but never seem to come across any SJ's.
I believe it will be a nice looker when finished up.

What was the stock make that came on it ?

To Add, Being a 2,5 mil UEF... Is the receiver stamped on the rear as being a Sub Contract made... letter: B, S, T, W,WTA or WWA ?
