The screws line up on my pre 64. It's a long mag. box.
The one in question is the one at the top.
Blackburn bottom metal is pictured beneath..it's a little different..

Could be a Dakota brand, before Sunny Hill started making them. I have a post64 that has the same type bow.

Here's a couple more pics..

A friend of mine has had this for awhile..along with a semi inletted stock. I thought I might do something with it later.
There's no markings on it..

I assume the action has to be modified for this to fit. What all does this entail?
Thanks,
Terry
