There were certainly 2 versions of the 1960-63 parts book, the later version including some changes up to frame GA7 11101 which started the 1961 model season and the earlier version not including the Triumph type 4 spring clutch.

To cope with modifications to parts and new parts introduced BSA issued unillustrated Parts Service Bulletins to dealers giving details. These were issued in series prefix GA for the twins, GB for B group singles. GC for C15, GD for Bantam, G for all models, N for new parts......... there were a lot of them issued.

So our parts books may not show a complete picture.

Dealers/storemen would use them to ammend their books.

The most famous of these parts bulletins probably being G21 from April 1962 which listed RGS parts and N8 from August 1963 which list late Super Rocket and RGS parts (plus some A50 and A65 parts)

Below are 2 bulletins showing the general layout.

It sounds as though 00-5086 strictly applies for all models from 1960-63 with some changes over this period reflected in additions to 00-5086 but with others via the Parts Service Bulletins. I assume the basic A10 models (not RGS or Spitfire)  produced in 1963 were largely the same as the in the previous 3 years although I'm curious about when and where alternators were fitted.

Alternators were fitted, together with a dynamo on some Police specification bikes from 1956. Not all Police A10s had an alternator fitted, it depended on what the customer specified.

These were fitted in CA10 engines until mid 1960 when the alternator bikes adopted the large journal crank. The engine series then changed to DA10A prefix. less than 400 of these later bikes made and many of these were exported.

Great photo - note the tyres with blackened sidewalls - must have been a former marine.

Thanks for the picture Julian, Its a pitty not more than 400 were made as this model with a later 12v stator & rotor would make the perfect A10.

They are a disaster as the stator is bolted to the outer cover so it is near impossible to get it centered on the rotor so the output pulses something fierce.
Not too much of a problem is the bike was fitted with a car sized battery to smooth things out but a big problem if you are running a std 5Ah motorcycle battery.

Never seen one up close, but is that shiny cover at the front of the primary case just a tin cover? If so wouldn't it be possible to access the rotor/stator from outside on assembly & slip feeler gauges between both to get centred  before tightening the cover fully? Or did they bugger it up so it can't be done .

 In the picture there is something mounted to the front fender, it does not look like a rocket and looks much further forward to me.

 Anyone know what that is?

Looks like a small plate. Probably says "I am the law!" Here's Judge Dredds', later Lawmaster model:

Digging deep into the grey cells I think it was the late 80's when the front number plates on motorcycles were abolished.
Some important persons son would have claimed to made the bike unstable at speed ( which they did ) causing a collision.
We had been advocating to have them removed from as far back as I can remember.

 Is about what I reckon too... Beeza's first rego ran out in '84 and it had them (still have them both,but don't tell anyone)- bought the XT600 in '87/8 and don't think it had a front one, rego'd the Gutzzi in '92 and no front one ever, so was definitely somewhere in between (at least in the sunny state)

Getting a bit off topic but I think it was late 70's -early 80's. My new 78 XL500S had one, my new 81 CB750F didn't. I remember you could tale the front and back plate in and get a new iridescence one for the back only.
The fun police had to change all the fixed speed cameras to rear view as loosing too much revenue from bikes.
