Hi Dave .... without seeing inside, it's fair to say most of us have tackled worse at some time or another. The Hi-Top is probably the machine with the highest production run ever. And is a style calssic (in my humble opinion) You'll find other postingson here that refer to it and explain the history, including the Sega connection.
Yours reminds me of a girlfriend I once had, looks attractive, seems to have the "fun" bits but most of my mates had got there before me and tampered selfishly.
Others may correct me, but from an external look it appears to be early 60's, if you peel the formica off, chances are you'll find oak underneath (why the hell did they do that?) I seem to remember there was a fad for adding a hellish electrical solenoid gubbins (attempt to modernise) on the payout, hence the nonsense about jackpot and lit lions, I had one of these once and ripped all that twaddle out of it.
You appear to have the correct coin escalator in the little window above SILVER BELLE but no jackpot (jackpots weren't always fitted but are nice to have) Internal photos will confirm or deny both statements.
Yes, you're right payout tray and corresponding surround trim are gone.
Unfortunately I have neither to spare, however they do crop up on e-bay UK in fact I'm sure there was a tray on just last week (can't see it now so it must have finished) Many of us extend our searches to include E-Bay USA. failing all that you might want to contact Metal Form Products USA (firstname.lastname@example.org
) his e-bay user id is nimblelass his catalogue which lists wonderous treasures is a must to have.
Let's see what it looksd like inside.
