I tried for days to get the pins to bind... thinking that the plug was frozen I sprayed WD40 in it to see if it would unfreeze. After 2 days sitting there I tried again... no luck! Well today I was playing around with it again and found that you have to pull up on the shackle and apply tension to make the pins bind... I am in the process of figuring out how to grow a 3rd limb so I can impression this lock...lol
Here is the keyway (it uses a flat key)

When I get the key done (if I can do it) I want the top of the key to match the symbol on the lock.

Anyone know anything about this lock? when it was made?
Thanks,
