Johnny, did I see that you picked up an M42 Pentax recently? Maybe worth a look? 163369844605. There is also this 202507940700. I did manage to score a Pentax 50mm f1.7 for a fiver plus post as it had a filter stuck to it. I carefully cut two slots with a hacksaw and used a lens spanner to unscrew. It's now living on my older K1000.
