The 7 inch full width iron hubs were used on the standard A7 twins 1958 until end of production.

The same hub but with an 18 inch rim was used on B40 and the early A50. Spindle shorter on the B40.

Agreed, take it off with the gear still on and get it on the bench.  The short answer is , yes you can put quite a bit of force on, its not the end of the world if you have to straighten the pulley .

The full width hubs use a plain spindle into clamps on the forks and the 8" single sided uses a threaded spindle but there are probably work arounds.  Mine has the A65 TLS but that means getting the brake plate build up with weld - and not as the PO did on mine with a spacer behind the bearing to shove the wheel over and leave the brake plate held on by a single thread

You’re probably right, it also looks very much like a C15. I’m surprised, because the previous owner spent an exorbitant amount of money on her and both wheels were build by Central Wheels, it’s a wonder they didn’t question it

While we’re still on the subject, do you think an 8” Single Sided brake would fit? I have one on my 55 Shooting Star and it would give a TLS a run for its money

I suggest, don't remove the gear. Remove the timing cover with the gear still attached. When replacing the inner timing cover use a spare intermediate gear to set the cam timing, remove the spare gear, then fit the timing cover with gear. Alternatively, the advised BSA method is to remove the inner cover with gear still in place, heat the dynamo gear then hit the end of the shaft with a soft faced hammer or aluminium drift. If you use a puller on the dynamo gear you will most likely distort it, particularly if you haven't applied heat.

keep the puller very tight get a piece of brass and a hammer and strike it on the flat bit on the gear it should come off unless it has loctite on it for some reason

I have to overhaul the breather on the BSA Goldflash 1954. To do this, you have to dismantle the intermediate housing and the timing cover. To dismantle the intermediate housing, you have to remove the dynamo gear, but now I'm having problems because the dynamo gear won't come loose. My question is: is the gear really on a cone and how much pressure can I apply or should I try using heat? Many thanks for your advice.
