Bitsa, you can use a drill to find the ID bore. ie, a 12mm drill bit  ;)

On these masters it should be 12mm to 14mm off the top of my head.

Fantastic Trig you never fail to amaze me but the biggest drill bit I have is 11mm.Did a rough measure with a tape I know not good enough and came out 13mm.Guess I am knackered after cutting down trees and bushes will give it ago again in the morning

If its 14mm the normal K series seal kit will fit, just some of the later ones did not fit the check valve at the end---gawd knows why

Bitsa, how can you lose a vernier? It's not like a small washer or a carb part. Have you looked under your seat ;D

Thanks for looking Mick I bet all yours have the plate and tube but as usual the krauts have come up with a kit not cheap/Our bruvs over the pond have told me its a year of one type and now have the part number and that's only because I posted has the states scrapped all k7s :P :P Part number 45530-404-315 cheapeast so far 53 euros ouch when a pattern master new is 58 euros.
Trig they have probably fallen in a box somewhere and on top of that the missus has told me she has been in there so I will have to go through all the box's again :-[ :-[

Have just sent you the numbers stamped under my master Cylinder and also the seal kit number. Master cyl number is 2 k 3 it has a plastic res which is the same as in the k7 parts book.

Thanks guys for ll your views
Got prices from all over and DS is the cheapest for a repro has anybody had one and what do you think of it?
I have allways thought and still do Honda is best but when a repair kit costs more than one of these complete is way different you have to think.
Kits from USA real cheap but you gain nothing with post on top so over to you DS fans
Cheers
