These two Molnijas just arrived, I'll use one in a future Panerai project. The 3601 movement was made using Cortebert tooling in Russia, as you may or may not know the Corteberts were basically re-badged with Rolex to power early Panerai watches.
Be aware though, there are two types of 15 jewel Molinja/Molnia movements, the 3601 and the 3602, the former being the one to go for. Why? because it has a brass holder for the centre wheel and the plates have the same finish overall as the original Cortebert/Rolex.
Both movements are in desperate need of a service, they are gummed up, stiff to wind/move hands and generally bereft of oil, in fact I would guess they probably haven't been serviced since new from the mid 50's...one's lost 2 mins in 24 hours, the other 5 mins.
