Prontor SV repair

[zozur]

Hello
I have this shutter in two cameras - Nettar and Ikoflex. In both cases slow speeds doesn't work correctly -
shutter stuck and I must push lever to fire it. In Ikoflex bulb time doesn't work - don't stay open but works like 1/30.
I only find Prontor SVS dissembling info. Anyone have tips or service manual for that shutters?

A Nettar is not that difficult to service actually. You need small screwdrivers but that is about it. I could do it but I am located up north from you (Szwecja). Just be careful and use proper screwdrivers....
