I’ve acquired a Beogram 1202 which is in great condition but unfortunately the tonearm positioning / cueing is not working. I've had a look at pictures on the net and it looks as though it is missing a flat clickspring (I think that’s what it’s called!) as shown in the photo. Could anybody tell me the approximate size of this so I can fabricate one  or advise where I might source one. Many thanks in advance. Login to view image
