Savage No. 4 (T) Scopeless stamps?

[Warren]

Er....... What's up with it Warren? Or am I missing something? It looks like a No4T without the T (or covered by the paint) and something barred out on the fore-end - unless it's the S51 barred out. But if it is that, it LOOKS like it reads ???1.

Scopeless No.4(T)
No T on the receiver....that we can see. (or cannot see as the case may be)
TR on butt socket....
S-51 barred out..obvious
Retake of the first picture.....A little better focus
D6 on the top of the butt socket.
