Material for coil bobbins?

[Geaney]

Thanks Gary, I've attached a photo from the original set I restored and you can see the two coils mounted on the right hand side of the chassis - the lower one is a single coil and the supper one has two coils on it. There are no slugs fortunately. I'm new to this coil winding stuff so I figured I start of with trying to reproduce the lower (single) one first and see how it goes. I'll PM my address and if you could spare about 3in of the paxolin tube that would be brilliant. I'm happy to pay postage of course.
Cheers, John
