New member here with no prior knowledge of these machines but I am mechanically inclined so learning then helping shouldn't be a problem.
The only machine I've owned was a Bally pinball that needed no repairs in the over 30 years I used and abused it prior to selling when I moved.
I just picked up two Gunter Wolff wall mount machines.
A Rotomat Jewel and a Duomat.
Both are working machines.
Both are unlocked but no keys.
Both currently use Canadian nickels but I don't think any parts were changed or altered.
The Rotomat Jewel:
-- The case is complete in fair condition with some chipping top front edge.
-- The plate on the side near the trigger arm is cracked and the top stop broken.
-- The outer metal has been painted a John Deere green.
-- The the first and second wheels always stop on potential winner numbers and the third wheel determines if it gets a payout. (Don't know if this is normal).
-- The front glass is solid black blackout for the background. (It's a 1959 model so I don't know if this is normal).
-- The payout is always 2 coins if landing on any payout position. ( think this is an adjustment issue but don't want to touch it till I learn more).
-- The arm and outer metal parts need painting.
This post is to say hello and my information post.
Any help or advise questions will be posted in the appropriate area/s at another time.
Will be browsing and wish to thank everyone for allowing me the opportutity.
