Last summer I bought a job lot of all the spares and special tools from a guy in South Jersey who was getting out of Brit bikes.
I am only now getting around to sorting out the tools.
I have identified all the marked Triumph tools but there are various extractors etc which are marked with MCA part numbers.
Now I know MCA stands for Motor Cycle Accessories and that they used to be located (in the 1960s) In Aston in Birmingham UK.
My question is----does anyone have a list of MCA part numbers and their applications?
The MCA part numbers I have are:
MCA P110/66
MCA F155 (might be P155)
MCA P158
MCA P189
MCA 110/77

Just to make life inter4esting there is also a tool with what looks like a factory marking which is stamped K&N T-101

Any help would be appreciated.

If you type in the second part (i.e.-no "MCA) you get a description.
Or email them ? They don't sell to the public but might tell you what it does

Most MCA special tools I've come across have been made of something weaker than zinc!


If anything other than a blank space is visible here, something's wrong.

Anglo/Tigernuts/John---many thanks for your responses
For anyone who is interested this is where I have got to:
a)MCA P110/66 and MCA 110/77
The 110 range are clutch extractors.
They include the equivalents of:
-- 60-1861 for Triumph 500/650s
-- 61-7014 for Triumph T140 (external thread 1" X 20 tpi)
-- DA50/1 for BSA/Norton/Triumph
-- 61-3766 for BSA A65 from 1966.
The suffices at the end of the 110 designation are the differentiators I think for the different applications.
However I cant find any reference listing to say what suffix is for which application.
b) MCA P155
60-2213 Cam wheel extractor for Triumph twins
c) MCA P158
61-6019 Crankshaft pinion extractor for Triumph 350/500/650/750
d) MCA P189
Rocker spindle extractor for Norton Commando

Still no idea after extensive searching for K&N T-101 so have to conclude that it is a "private" stamping.
Will post a photo and see if anyone recognizes it.
Thanks again for the help to date.
