Annoying knock from camshaft front pulley area

[flywheel1935]

IMO the insurance price increases are the downside of the of old car values rocketing in the last few years.

My 1937 Ruby (done about 91,000 miles in total) has a similar knock coming from the vicinity of the front camshaft bush.  Only at a very slow idle.  The engine was reconditioned (allegedly professionally) for the previous owner about 1,000 miles previously.
I cannot detect any fore and aft movement of the camshaft when I lever the camshaft pulley with a big screwdriver.  Would there be a better way to check this while the engine is in the car?
I like the ideas for refastening this bush given in this thread and similar ideas given in other A7 websites.  However, is there any way to sort it out while the engine is still in the car?

I also had my Ruby engine rebuilt by a so called 'professional'
, and the cam bearing moved for and aft so much that the timing was out by over 20 degrees at times, maybe it was the same 'builder' !!!!
