Could be frustrating.
Works fine now but originally my Helios 44-2 was mounted upside down. At front of the adapter three screws needed to be loosened to rotate the mount 180 degrees. I did that but had to find out what sort of screws they were. Not immediately apparent. Discovered it needed a T5 star pointed bit to do the job. Hope this helps any future buyers.
