Hi and welcome. Loads of Vostok enthusiasts and experts on here; one or two have helped me out brilliantly.
I suggest changing your thread title to ‘Looking for Vostok help’ as it might get a bit more response. Mods and Wreckers is visited less than other parts of the forum.
In any event I’m sure someone like Lampoc will be along soon to help out.
Best of luck, looking forward to seeing some more pics of your watches.
