I picked up a repro scope a few months ago on Delcampe (french ebay thingy) for my british re-enacting I have no idea who the makers is, but its labeled up as a MK3 when its clearly an mk 1 or mk2. The optics seem to be very ok but as its more a display piece (firing blanks) i could say wether it works for shooting. The downside to it (apart from the wrong MK ofc) is that when i had the work done to fit it to a No.4, it turned out the part of the bracket (the scope came with the pads and bracket as a package) that holds the scope straight was way off and i had to have some work done to it, its fine now luckly.

I have added some pics if anyone could tell me more about this scope
