Carbine stock marking - help needed !

[Patrick Chadwick]

Thank you Jim for the quick reply.

I had found that site, and knew about IO /OI. I suppose that the stock was supplied to Standard Products by Overton, and therefore marked Std Prod before the rifle was assembled. So it would have been an genuine part for a Std Prod carbine. But who/what was RWH? Standard Products acceptance/inspector???

Oops, thanks Charlie, you posted while I was typing. All clear now. If you (or anyone else) finds out the name behind RWH, please post it here!
