Earlier than 70's I think. Hub is early, rivetted together Harden like.
Double fixed hub, equivalent to 40 spokes.

Have seen this model previously but do not know maker. First guess would be British. Just imagine what lacing must be like! :mask:

And one would require spokes on the order of 600mm in length. :openmouth:

I would be interesting to call your LBS and tell them you are bringing in a wheel with a broken spoke and ask them about how much would it cost to replace it. Then show up with it and announce proudly, "Here's the wheel I called about, how long will it take?" :p

I think I can guess the reaction in this instance lol.
Although to be fair, they're usually pretty good when I go in for random spokes?
I'm guessing you'd have to get 'penny farthing ' spokes and cut to length and thread yourself.
I don't own this wheel, but I may be involved in cleaning it later in the year.
Will be interesting to find any identifying marks.

I'm back - Constrictor hubs from the 50s,
That is their patented Circum disc hub

According to Peter Underwood, they're quite rare.
I guess a collecter's dream could be to have a classic frame equipped wholly with Constrictor equipment including an Osgear plus D.C.W front changer, hubs, rims, wingnuts, lamp bracket, toe clips and straps, pedals, honking rubbers and the combined handlebar end plug and container (sold with rubber solution, patches and sand paper). It would be too much though to hope to find usable Contrictor tyres or tubulars to complete the showpiece.
As Peter implied, Constrictor also made Osgear shifters.

@bulldog1935, I salute you Sir!
Fantastic information, I guessed that it was pretty rare, judging by the fact that many venerable expert enthusiasts (plus moi) on Saturday evening had never seen anything like it.
Do the constrictor rims have any identifying marks other than decals?
Thanks again, and enjoy your ride tomorrow!

The Flickr I linked has some rim catalog pages, but they could be prewar.
From what I gathered from Peter, they were expensive, which limited their market.
But I would guess anyone who could afford those hubs would follow through with their rims, as well.

WOW!

Thanks so much for this outstanding post.

Fascinating to see how these are done.

Find the joining of the barrel to flange as interesting as the spoking arrangement.

On some cheap five-piece hub shells the drive side flange on the rear can have a tendency to work loose,

These are really done right.

Much appreciated here. Hope you enjoyed a fine kayak trip.

you're welcome, I took it as a challenge, and searched it down on Peter Underwood's Classic Lightweights database.

and thanks, had two great coast trips this fall
https://thecabe.com/forum/threads/rockport-trip.119812/
https://thecabe.com/forum/threads/arroyo-paddling-and-fishing.120820/
long ago I ran out of things to prove in fishing - I've fly fished twice on national tv
so I fish hard when it's called for, but the fish are gravy - what's more important are good friends, many interests, and good food,
My success is being able to plan and execute a trip that gives success to my novice friends and exceeds their expectations.

I spoke to the owner yesterday and he was glad of the info.
He's bought his own blaster to clean it up and will probably just display it.
He has some lovely, unusual machines that I'll try to get some photos of soon. Thanks again to everyone that helped.
