Curl,

Congrats on a pretty little stick! I had seen one of these at a dealer here about three years ago in the same condition as yours, poor sod was dead-sure it was a .450/.400 and was quite baffled when I'd told him it looked like a .40 cal but definitely wasn't a .450/.400, not even the 2 7/8" case BPE, much less the 3" or 3.25" version! You should have seen the look on his face when he tried to cram a 3" round into the chamber!!
I remember vaguely that he wanted 15k INR for it, approximately 265 USD given the currency rates today.
