long time ago I bought this gem with exakta mount and modified it to Nikon mount but lost infinity... today I finished the work and infinity IS available Wink I will post some photos later... here are a couple of photos of the lens





wide open at 1,5m with flash bounced off the ceiling

What was the procedure to reach infinity? Shaving or recalibrate inside?

I dismounted the exakta mount some grinding was done and then I glued M42 to Nikon adapter on it, to reach infinity I added a grinded macro ring with Nikon mount...
here you can see the exakta mount and glued-on M42 adapter
