I finally have the front hub that I am happy with, thanks Simon.
and the new strong rims in the Constrictor Asp style

the hubs and rims can go off for measuring and the spokes can be ordered from Britain.

and playing with the front end jewellry

if Dare handlebar grips were good for the 1946 Hobbs of Barbican, then they are also good for the Blue Riband.
These came up on the British evilbay.

I was the only bidder (no surprises there).
So red grips to lift the conservative appearance.
And this needs to have red elsewhere.

Simon (a cycling friend who has a good eye for detail) has suggested red toe straps.
And I have thought I can have a red highlight on the chainset.
If you know your late 1940s/early 1950s British lightweight rare components you will know where this might be going.
Hobbs of Barbican produced some top end components under the Lytaloy name.

They are highly sought after whenever they appear.

But one of the rarest items is the Lytaloy chainset. Rare because they often cracked. It has been suggested to me that current knowledge of the alloy grades should provide a grade that will work.
So I am now chasing another rabbit down a hole and my drive-side survivor is being modelled by a professional. If that works, the model will go off for CNC machining.

Then I can paint the area around the name, and that will further repeat the red in the grips, and balance the appearance.
Just like on John's Alcon
But there will be a set of Williams cranks in the intervening period.

I had the good fortune to buy a non-cracked NDS crank for the Alcon. Happy to send the cracked one to you if you like Phillip.

that would help a great deal in modelling the 'missing' arm.
thanks

I wouldn’t be using a CNCed crankarm modelled off a thin section forged one. If the forged item use to crack the CNC version will not last long.

The CNC machining will be done by someone who makes crank arms for these. If Mick has concerns with the design, he has a clarity in his communication style which even I could not misinterpret.
