Many Belgian made revolver have a bore diameter of .44 to .442. The brass which fits those also varies, some can use a standard .455 Webley, others need the rim trimmed down etc. I don't think the cylinder has been reamed. I also don't think it is a .450 Adams, maybe one of the European calibers. That's why you have to measure everything. I would try to put everything together first so you know if it is complete and works. I have taken several of those apart and assembled again. I was tempted to buy it when you had it listed but that would be a gamble. Not that I would not be able to put it together but you never know if it works until you have it assembled.
