HERCULOK Cylidrical Padlock by ILCO UNICAN

[femurat]

I recently got this padlock locked. It was used to test a tubular lock, and the test failed. I picked it a few times but the shackle didn't open.
One evening I lost my temper and drilled it open... maybe I drilled too much. I thought there was something wrong with the actuator so I tried to reach it trough the lock, but failed.
Then I decided to drill the retaining pin and disassembled it with little damage.
I still don't know what was wrong with the padlock, I suspect the actuator was not correctly connected with the lock.

The lock is quite uncommon so I'd like to repair it. Its body is 50 mm wide and has a 11 mm shackle diameter.
Hope to find some spare parts: the (aluminium?) retaining pin and it's steel cover, the short side shackle spring that is now broken in half and the most important one, the part that connects the lock with the actuator, it's the piece that has a spring wrapped around it, that was slightly damaged by the drill. Let me know if you can find these.

Cheers
