Hi,
Any thoughts on the below, the price seems good and I've heard that most are 'patterns' now anyway..............
I also wanted to confirm that the master cylinder was the same throughout the production run, mine is a 1955 car.
Many thanks,
Mike.

Be prepared to have to dress it to fit. Some of the repros are (or were) a tad too wide.
Regards
Declan

When I clicked on the link you give and went to the page, just above the item you are writing about is a suggestion showing a lockheed one for a Minor, I'd go for that if I were you
P.S. As Declan says you will need to file a little off the sides to get it to fit as I had to.

To answer the question as to whether the master cylinder was the same throughout the production run - it was not!
There were two master cylinder fitted to the Minor during its production run and they had the following cylinder bores.
Pre 1962.......................7/8" internal dia. Pt No: 17H7423 (BMC Pts list)
Post 1962......................13/16" internal dia. Pt No: 17H6613 (BMC Pts list) / CBS144 (ESM).
It appears that currently only the later master cylinder is available as a complete unit but seal kits for the earlier master cylinder is available.

You must have bought the last one as they are now out of stock.

Thanks for the info. Would it make a big difference using the later 13/16" master cylinder, rather than spending an age looking for an early 7/8" one?
Best wishes,
Mike.

The later one will work just the same.
As already mentioned they are an extremly tight fit, I had to grind a small amount off bothe sides of the last one I fitted after a lot of cursing and some skinned knuckles.........

Yep. Fitted a new Lockheed one last week to the traveller. Had to shave a bit of each bolt hole. But with no cursing David.
