Subject: [Healeys] 100 BN1 Laygear Numbers

Greetings

Just started looking through a couple of boxes of 100 BN1 parts that came my way a year of so back.

I was surprised that at the bottom of one of the boxes was a 100 BN1 laygear or clustergear.

It is in very good condition and is stamped with the part number 1B3474.

The number is familiar, but can anyone verify it for me please?

Hi Patrick,

I checked a table of gearbox part numbers in my archives, but part number
1B3474 is not listed. Is it possible this is from a very early BN1?

If any experts on this list have the specifications for part number 1B3481,
you could compare those to the gear you have.

Regards,

Harold Manifold
