Hi Guy,
Here are a few pix of the bass we discussed and I’ve never seen one like this before. In my opinion it probably originated from East Germany and dates back to either the late 1950’s or early 1960’s. It may have been made by Musima and the pick-ups are Rellog but, of course, it may be a one-off. If you have any ideas please let me know.
I have just put new strings on it and it plays really well.
