Last pics!

First pic is two original brown Bakelite knobs from my Ekco A22 alongside the two replicas.
Second pic is the original small knob alongside the replica black one.

In fairness to my chum who milled the 8 notches on the four 'Bestone' replica knobs for me, the last pic shows a knob on its mandrel in the chuck of the Bridgeport milling machine, on which the last notch had just been milled.

I'll be taking the knobs to Hornsea radio rally tomorrow morning, where my chum John ('60old john' on the forum), will do a quality control inspection for me!

I hope the thread is of interest, not too far off topic away from the electronics aspect of the hobby, and might encourage others who are suitably equipped, to try their hand.
