Hi Terry
I can recommend this chap, Henry Powell, here is the link-
http://www.1armedbandit.co.uk/To be honest, this was not an ideal choice for a first machine as it will cost you a LOT of money to get this right.
I would think about taking this to Henry Powell as you are new to this and he is in the UK.
You can discuss all the issues face to face as there are Many!
I am Happy to admit that I love to see new collecters discussing there first machines on here, but there is only so much you can do via the forum, especially with someone who lacks experience of these machines
You could spend months posting on this forum and make very little progress with the actual physical work required!
I am sure Henry would welcome looking over it with you and discussing the various options open at no charge.
He has done a lot of restorations of Rol a tops and he is the man, in the UK, anyway.
Good luck
Nigel
