Mike:

I just checked your link and you are dead on!

The differences I see are:
--mine is less shiny but the metal is not pitted.
--mine is in need of a new nipple
--mine has much cleaner inprints in the stock on the side opposite the hammer.
--mine has assorted minor dents in the wood from use.
--in the strap behind the trigger guard, mine has a W rather than a C and a J stamped in the stock just behind that.

Other than those very minor differences, they are identical twins. Thank you very much for the link.

Next question:
Is it likely I can find someone to replace the damaged nipple and just how much cleaning and polishing is allowed without altering its value? It is clear that the one for sale has been extensively cleaned and polished.

Thanks
Bart
