I hate to sound clever (well maybe not ) but I have two verniers. One Mitutoyu that is about a million years old, but the display has decided to pack up, and a cheap modern one that cost about £12.
I am one of those sad creatures (although I am now at an age when I no longer apologise for it) who like a 'belt and braces' approach.
If the proper toll was around the £20 mark then fine...£40 is a bit steep. But thanks for the info.
I'll have the pipes of tomorrow and see why oil is dripping out of the front cylinder. Can't wait
Mike
