New unissued/unnumbered No1 MKIII nose cap.

[Peter Laidler]

Simple part like that it'd be easier to put it in your bench vice and file it. So simplicity would be the answer. The only reason some parts are numbered to match on rifles is to preserve the integrity of the accuracy and of the hand fitted parts..., like backsight slide, fore-end, nose cap, magazine...., you know what I mean.

I have renumbered zillions of parts for re-use. Never worried me or the eagle eyed examiners/out-inspectors...., the people who REALLY matter. But I agree entirely with Patrick
