None of these machines have any manufacturers, distributers or operators names on them. I have always thought that numbers 1, 4, 5 and 6 are English machines (Allwins) with the paperwork changed and 1, 4 and 5 being rehoused in new cabinets. I think that number 2 with the automatic payout is probably Australian with the payout trim piece possibly coming from another machine. I have seen two other examples of this machine. I believe that number 3, the electric coin payout, is Australian. I have thought that number 7 may be Australian.
I wasn't making any claims about these machines being Australian, merely that I found them here in Australia and as they have been in my collection I had them ready to hand on my computer. When I get the chance I will go through my photos, scan them and show the machines that Rory mentions that he found the Australian design patents for.
