Just checked mine, which I bought a while ago, already adapted to M39.
It looks like they gutted an Industar-50-2 and used its barrel and focusing parts to house the Helios-33 optical block.
The mount seems changed from M42 to M39 due to the shorter register distance of the Helios-33.
I'm getting sleepy now, but can make pics later.
PS - you reminded me I still should have a look at how to adapt the Helios-89 that I got a while back |
