IMHO rifle scope & bracket are all fine -- an honest mis-match as stated. Photo's aren't sharp enough to tell, but bracket cradle ends may have been filed up tho' I can't make out if they've been renumbered......I say this as they just look too 'clean' to me (though bracket in toto is def original). I also cannot tell due to the quality of the pics, but I suspect the scope adjustment tool may be a repro as well as the lens caps.
But all in all, it looks ok to me....
(Incidentally, I have two numbered reasonably close: AS 03XX & AS 41XX).
