Hello... Anyone?

It looks like a Watling slot machine lock to me, probably a Blue Seal or Rol-A-Top.

Hi Forum, There is writing on the barrel ODJ 1610 Which makes that lock a JENNINGS Back Door lock for a Deer scene type slot machine. The blank key needed is the ILCO 997 JA that WILL FIT UNLESS You can find a Yale key to re-key it with.

Thank you all for getting back... It is a strange lock, I went on google to find any info about it and was unable to find any.
How much do these style of lock go for? Are these rare? Hard to find? Thank you...
