Can anyone give me a rough idea of the thickness of leather used for read valves please?
Thanks

Frank offers much the same selection of leathers. When replacing reed leathers, first match the thickness and trim the leather to size.
Some treble & bass reeds will need reed tensions (boosters) and come in Bass,Large,Medium or Small.
For Pic's of the sizes see here -

I would be interested to know what the difference is between ventilli and viledon valves please

 

[JIM D.]

They are both plastic (ventilli) As a rule of thumb plastic valves (ventilli) would be the sizes used for the treble side and plastic valves (viledon) would be used on the bass reeds. They are both commonly called (ventilli or plastic).
Higher priced accordion models from Italy today come with Plastic treble valves and most all have leather bass valves.
