I got hold of some nice BMC literature, consisting of +200 service bulletins covering 1962 to 1964, most of them relate to Mini and ADO16 cars, they contain very nice information there. I plan to scan them once we go out of "lockdown" and if there is interest/it is possible, Mark can add to the technical section.
Meanwhile if anyone is looking for some particular information among these 3 years i can search and send pics.
Have also some BMC service bulletins from late 60, early 70's but in Portuguese , maybe not so easy for most members.

Oh, i have one question... what "GN" stands for when identifying the Service Bulletins ?

Some more examples,
Cheers

Very nice. Interesting reading.

These Service Bulletins are great info and reference .. my interest was your example of the Reversing Light "Gearbox Switch" showing the " Plunger Pin Part Number 22G351" .. for many decades i have wanted to know the BMC official Dia; & length of that small round Pin & it still unknown

now i know, you posted on TheMiniforum and i've found it while searching for the same plunger!

Thanks

So we are all happy now that we have found out the correct size of our Plunger .. Big Thanks.

To complete the BMC specification of the reversing light facility here's the engineering drawing for the Lucas switch part 34887 (also known by other part numbers).

that info answers another question of what is the Lucas Reversing Switch thread type & size .. so now i know "5/8 UNC x 11tpi " .. Many Thanks.

This would be such a great resource... you guys help us all so much
