The two most difficult to source pieces of the Rolleikin are the counter knob and screws… and the leatherette patch. I had to buy two sets and a few stray parts to make one complete working set.
Remember that the Rolleikin was made over a good number of years and packaged for cameras that need a counter as well as some Rolleiflex cameras that had built-in 36 exposure counter. So while some Rolleikin kits are missing counters, others never had one.
The counters also seem to fail easily. Not one that I bought worked reliably until overhauled, and that was a thankless task. Not the most robust mechanism.
The screws are nice to have because the long head makes installation a bit easier but substitute screws can work also.
Keep shopping eBay etc for bargains as they exist given enough patience. Good luck.
