TSS night latch SPP

TSS 6 pin night latch/ rim cylinder. Tok, light yo medium tension and set 1 then 4, high lifts, take tension down to light and use light picking, bounce around between remaining pins, open.

I have opened this months ago at least twice, as I like to open a lock a few times before I move on. Haven't touched it since now, to be honest was at it fir days.
