Realisation - kicking myself. Been waiting for the right Bach Craven 105 to come along and only just realised that I actually want a Craven 141... no wonder the front didn't look quite right. Doh!
I was hoping to get one/two as I used to use these into Kings Cross... before the 313s came in. So would sit with 55s, 31s, 47s, etc... but a check on a book I have describes those as class 141. Bother!
