I'm not certain how you can be "sure" that the in the white parts are original; I'm equally as sure that they are not. All the parts would have been blue/black when originally mfg., except the latch spring, which would be colored by its heat treatment process.One of these webleys ( the one with the missing latch pring ) has an in the white trigger and hammer and a couple of other bits, I am sure it was this way from new, is this normal ? I don't think it's a commercial version as it has military markings. It's picture number 4 above.
I sold three of them for over 1000 each. All three sold in two days so I guess I did not ask enoughPretty good way to drop the value a bit.
