Probably a variety of stuff,
The bikes got one Smiths Tachometer and a Veglia speedo, both in long holders that have been painted badly in black to hide the road rash on one of the holders. It's a 71 (mainly) so would like to go back to short alloy holders, so this I think means finding a useable smiths speedo.
Just getting into the Norton thing, have run older airheads for ages.
