The watch database on Jules Borel just have the 300P30HN02 listed. The latter is no longer stocked, or at least not by Cousins, and I can't find it on any of the normal sites I use. Cousins have the LN03 variant, though.
For 18 quid I'm inclined just to give it a try, as it is a domed Hardlex crystal that I am not sure would be easily available as a generic. Crystaltimes show a SNA029 on the same page as their sapphire replacement crystal for the RAF issue Gen 1, but as its only shown in passing I have emailed them to see if it is indeed a suitable replacement.
I have a case-back gasket and also the crystal gasket in the same shopping basket at Cousins, so hopefully if anything is untoward with the current ones I'll have spares.
The bezel doesn't appear to be (re)movable, and it's not listed as a separate part on either of the sites above, so hopefully the crystal can be replaced with it in situ.
Rodico - check
Pegwood - check
Pointy cotton wool buds - great suggestion and added to basket
Thank you again.
