Hi kheinen from me too.
The USA chaps are correct in that it sounds like you have two British 'convertions'.
Pics can confirm & date them but chances are they are Tom Boland (Leeds, Yorkshire) revamps using cobbled together old Mills (mostly) 10-stop gooseneck mechs and recased in a combination of rough aluminium or timber/lamitate garb. Circa 1950 - 1956.
Mostly all were 1d with max 12d coin payout with
original back doors, cashboxes, jp's and escalators thrown in the skip

- so a straight drop coin throat (how trusting us POMs were,,,,,).
Nic Costa's book and articles are the best references.
If you're UK based pop in to the
pennymachines web site.
(can I say that Mods?)
