Thanks. Mine definitely says: 'Not to be removed'. However, it (a) has knurling on the barrel, (b) it does have a thinner trigger compared to later examples, and (c) It has Webley moulded into the grips. I really don't think its a parts pistol, but I could be wrong, mainly because all parts have the same ageing and wear. Were examples known in the 1940's that had a combination on pre and post war features?
