Any photos of the "slim BT FE"?
I would love to see that.
Also would be interesting to know the length of the BT FE.
As everyone knows (and I know first hand) Winchester had problems with the beavertail breaking ("chipping" might be a better word choice) , and made at least a couple of modifications to the design. Many of us have worked around this with various means, depending on the age of the gun.
It would be great to see the INSIDE of the BT and see what the Big Boys at CSMC currently are making.
Back to your gun; let's face it. it is wonderful.
Enjoy.
