I’ve seen those coin acceptors before. It was so long ago I can’t remember who made them, I think they came from Germany. He might have to have a new face plate made and use something like a short drop Slugbuster or Secure coincoin acceptor, that’s probably not what he’ll want to here.
That's about all I knew, he was looking for a Keltner VA-3 but it turned out to be the acceptor since the timer runs by jumping the coin inputs. If need be I'm sure I can get a plate made cheap and put a short-drop acceptor on it.
