I did spot one thing, the coin slide that goes across the middle of the machine from left to right as you look at the pic, seems to be missing?

He he he. The thread re: grease very helpful and funny

It looks good to me.
I don't know what you mean by missing chute. Looking from the back of the mech you can see the coin overflow chute which has been cut across from hole to hole in order to spread it. This was done during the conversion from pfennig to old penny. It's likely that's the origin of the coin jam, those conversions tend to be a tad problematic.

Unless there's any nasty hidden problems or ageing to the Monkey Metal I'd say you got a real bargain there.

Personally I wouldn't trust it to somebody else to deliver. I've bought 4 in my time and always collected them myself.
95% of the value is in the glass front. You'll never replace it, unless an expert in silk screen printing and mirroring decides to tool up, which I doubt is likely.

Best of luck and enjoy

ps - coppinpr says oil and don't forget the gear bearings accessible via the back plate on the clock. Don't be tempted to remove the plastic cover and oil the cogs themselves, you're likely to drown it so it stops.

Appreciated thanks for the advice. I see what you mean about the coin slide, so the penny slide is at the bottom of the machine and the phenig slide in the middle, do I understand you correctly?

No, BP was pointing out that when the machine was imported from Germany it was converted and the hopper and all the Pfennig payout slides were replaced with larger ones for the old penny. At the same time various channels and chutes also had to be opened up to take the larger coin.

Thanks for clarifying that. So just because I'm having a blond moment (though I'm not blond ) does my machine have a penny shute or a phenig shute, cos the one in the pics sent to me has a shute at the bottom of the machine and one in the middle. Mine only seems to have a shute at the bottom?

your getting there,we have all tried to diagnose problems on machines before they arrive,its impossible.

It is true your machine has no middle chute but this is probably not a problem but part of the conversion . The conversion on mine utilised the original coin box(which you can see in one of my photos) so the coins going to the cash box needed to be sent across the back of the machine,this ment converting the chute,on yours I suspect that conversion company short cut the problem and took out the chute and let the cash box coins fall straight off the small slide you can see where the chute should start , because these have a wide case a cash box was most likely just placed under the slide and coins were allowed to drop into the box. By the time the coin reaches that point its no longer being used by the machine so it can just fall into a box. the benefit of this is you wont get a coin jam like I have in my photos

BP, am I right in thinking the plastic cover is missing from the clock? if so might have caused a problem

Yes Paul, the cover is missing of OP's clock.
I was confused whose photos belonged to whom.

I'd recommend removing the clock and gently testing it to check its function.
If it is seized you don't really want the weight of the machine bearing on the cogs.

Once out of the danger of stress, should the clock be locked up or dragging then soak it for a day or two in "Plus Gas" or diesel, until it can be eased back into service.
They certainly benefit from being kept covered, so recycle a coleslaw pot or similar.

Thanks guys, the fog is clearing here. I agree it would be better to diagnose when I have the machine in front of me. My skills in repairing machines is in its infancy so I will get back to you when I have given it a priliminary inspection. Love the idea of a plastic coleslaw pot for the cover, my kinda DIY.

The seller looks to be right, one of the two accuator bars is missing, the lower one looking at the picture. Also is the back missing as it was nit in the picture

Hi, thanks for your insight. If they are missing is there any way to replicate these pieces?

If anyone has the parts it's treefrog. I'd be surprised if he doesn't have half a dozen Duo-mat machines - just ask him nicely.

Thank you, I will send him a message.

I know you pinged me, but I am afraid I am not a source of spares for all, just happen like many to have one or two bits lying around. In terms of Duomats, I have 5, three good ones and two very rough projects. I might make one out of the last two, as such possibly I will end up with some spare mechanical bits and possibly a good glass front. At this stage, not made that call, so all I can do is measure that part which would be easy to produce a temp item that would do the job....

One thing I have never tried is whether the cabinets are the same size as Beromat type machines, as this may be a cheap source of a rear door.

I have a scrap one.
It's quite lacking in parts, but there are some cabinet as well as mechanical parts.

I shan't have a chance to give any details for a few weeks as it won't be accessible until near Christmas.

Thank you tree frog, will keep that in mind and maybe get back to you for further information.

Appreciated BP. I won't exactly know what I need until I can get eyes on and then won't be sure until I have asked a few more questions. But def will be in touch to see if you have what I need.

This one sold for £300 just over a year ago
