Spindle reduction sleeve, colchester?

[GraemeVW]

Anyone know what this is from? Best guess by me is mt5 outside but it's deffinately mt3 inside.

Came in a box of stuff that included some 6.5" center height colchester roundhead steadies and a L0 colchester catch plate so id guess its student/master, but would like to confirm.

It's probably a sought-after MT4.5 to MT3 reducer.

Could also be mt5 ... mine is

I wish, I'd be all over it like a tramp on chips.

A MT5 is about 1.7 going to 1.4 over 5 inches, so that would seem about right. MT4.5 starts at 1.5, so probably not one of those.

Quick rub over the outside with an angle grinder and it could be mt4.5.

I found a roundhead student one for sale that listed the same dimensions, so I guess it's confirmed.

That is an automatic vernier caliper? Good!

Lots of discussion as to whether it is MT5 or MT4.5

Either way, that is not the sought after M300 reducer as the dimensions don't match
