The pin is probably a soft one - the hard edge of the shaft digs into the soft material and the ultimate result it you cant tighten it, it just rocks. If the edge has dug in it makes it  harder to drift it out and you might need to carefully drill.

Source a good quality cotter when refitting, they come with different degrees of machined flats to suit different shafts/levers. I got some very good and hard ones form Dave Flintoff the Gold Star man.

Have you tried Autocycle?

Or Bantam John, Sheffield British Motorcycles?

If you have exhausted the UK suppliers try the USA;

"KJ" actually decodes as September 1973;

K = September

J = 1974 season model. (the season running August 1973-July 1974) so year is 1973.

Try the BSAOC site for numbers;

Your numbers are from early in the 1965 season (which ran August 1964 - July 1965)

The photo shows the commutator looking very dirty  and the brushes worn.

Unless you have cleaned commutator and replaced brushes the dynamo will not give its best.

SC3303/20 was originaly fitted to various Royal Enfield 250, 350 and 500 according to Smiths 1961 catalogue.

Whether it would be accurate if used on an A65 I dont know, you could always enquire at one of the Chronometric specialists.

Just one dimension - is the long rod 5/16 diameter, same as the short front rod?

Thanks
