At last put the pics on of the Webley No1, cleaned and assembled again, it was very dirty and dusty after sitting for years doing nothing but came out well.
It is either .442 or .450, not sure as yet, but is a very nice pistol. Research tells they were made in about 1863 ish, and then the new No 1 came out with fluted cylinder. hope you like it.
Sorry pics didnt came out
