I’d like to introduce myself (I’m Jon) & the machine I found a while ago in a local vintage shop near where I live in Surrey
From reading around on the forums here & some searching online, I believe I have an English-market model of a Wulff wall-mounted machine. The case is pretty battered, but crucially (for me) the mechanism just about works: it was sold to me as not working, but I discovered the last owner had tried using it with modern 2p pieces & I believe it should correctly be used with old pre-decimal pennies. Once I had cleared the jam, the system runs.
I’d love to be directed to any resources or knowledgeable people to help me restore this machine (for example, bent nails have been used to replace some of the pins inside the mechanism) both mechanically & cosmetically - as you can see from this image, the poor thing hasn’t been well looked after, but is still solid.
