Just bought this challenging project, is has frameno WM20-53729 and a later BM21 engine. As you can see it has the brazed lug for the sidestand and pillion footrests and the panniers. It also has a ribbed rearguard and was wondering if this combination of parts could be correct for this bike ??
Also any info on its history would be much appreciated. It has a russian fronttyre and speedo so it probably spend some time over there.
Thanks in advance, Regards, Michiel

Any idea when the first panniers were fitted ??
Wouldn't the short field stand have a conflict with the panniers or was there some period that the brazed lug was still there and not used, and they fitted the longer fieldstand ?? The longer stand also came (loose) with the bike.
Hi Henk, thanks for looking, pitty it is't in the keycards but I now know the factory date 
Hi Maarten, it was indeed not advertised (yet), comes from Dutch Lion, I saw it standing in the corner when I was there some time ago

If my calculation are ok your tank number would have been C4635317.
Here two photos with bikes with tank numbers quite close to yours so this is what yours probably looked like too when new. Your rear frame might not be the original one of course.

Nice pictures !!, Henk
On the first picture there is still the brazed lug for the short stand so the rearframe could be the original.
Also like the big 8" headlamp. But no more combination levers at that time if I look correct.
Thanks again, also for your calculation, Michiel
