Hello Omegoids, I may have posted this in the wrong place, so I'll try again: So I got my first twins! The JLC on the right was inherited from my grandmother. It was her brothers, he was an RAF navigator in WWII and KIA. The one on the left just arrived from a rag and bone mans ebay shop in France....got it silly cheap! (180 Euros and it works!!!) Question is this- JLC were never overly bothered about standard cases and used all sorts of suppliers as long as it was high quality steel. Very clear difference here in case design too....should I (can I) get it fixed or start looking for a generic period case in the same high quality (aviation) steel? Any ideas which omega cases would be good donors ...cases measure 32/33 without crown. Thanks for all and any suggestions...
