Interesting.
I think the 'locks' have been added.
(And if there is a key involved, it is absolutely tiny)

They are a perfect fit on an old Triumph.
And the purveyor of early Triumph parts sells Brookes replicas.
What these may have started out as ??

Looks to be something similar in about the middle.
Bicycles rule OK  ?

Congratulations !
On several counts ...

and the Spares Dept on New Park Road, close by, but does anyone remember, or even knew of, the Bike storage facility somewhere in the back streets close by the Spares Dept ?
This was a substantial warehouse behind local terraced houses, accessed through a gated tunnel and a small court-yard with a wooden office/shed.

Interesting.

How did it look ?
There is such a place just around the corner, at 6A Sulina Rd. The brick place.
There is a large warehouse out the back on the aerial view.
It currently is apparently a furniture place, with no indication on that front/garage door.

That reminds me of someone who I came across, who had a significantly large quantity of
Norton Navigator piston rings, in various oversizes.
We calculated that based on demand, he had approx 40,000 years of supply !!
He did have rather a lot ....

I've had a number of sprockets rebanded.
This is quite economical.

I shudder to think what getting a spline cut might be ??
As a one off.

I see that Villiers Services are obviously getting a range of sprockets remade
(if they are not buying up old stock ?)
At quite reasonable prices.
So in quantity its quite economical....

I'm surprised they don't have the model required here ?

You have tried Villiers Services for all possible choices. ?
They have quite a range

etc

What does the fitting(s) for the tail light look like.
Round/square/oblong 1,2 or 3 holes.

Finding anything electrical and original is a black science these days.
Usually you have to make do with replica/offerings. Or get very lucky.

Here is a smattering of choices.
Anything look suitable.
Such things were often quite small back then, usually owners now opt for something bigger and more visible.
Not being rear-ended by some noddy on the phone has much to commend it ...
