and certainly not in 1928 when foot change was not even common at the Isle of Man TT race!

I see what you mean, I hadn't considered that aspect of it.

Wasn't Harold Willis (Velocette) credited with the invention of the positive stop mechanism
- reputedly after studying the action of a farm reaping and binding machine.

Nicely made, but not by Sturmey Archer, and certainly not in 1928 when foot change was not even common at the Isle of Man TT race! That said, someone has gone to a lot of trouble, and personally I'd keep it as part of the bike's history.

The other option is to convert it back to how it was (worm clutch and hand change).

Leon

Why do you say it's a foot change? The bike came with a hand lever (also different from the usual sturmey archer, see the pictures above)
If I manage to put everything working, I will leave it as it is.

I agree with Leon.
That is not an original Sturmey Archer gear hinge and clutch operating system but as would Leon Id keep it fitted on as it is a real part of the bikes history.
Someone showed real skill to do the alteration and I would be proud to show it off. It really tells a story.

It may not be a foot change as you expect it to be but it dates from an early period when no one really understood foot changes so no surprise its not quite right.

Best of luck with it all.

I'm not sure if I put it in the correct place.... I'm just guessing.
The linkage part that goes down its solid, doesn't bend.

I've found the "gear locker pin", see the new image.

It's also curious that the gear lever midle hole and size, fits well in the gearbox case. I have to spend more time with this puzzle :)

Does this gearbox as neutral position?

Look what I've found. This looks to be the pedal to change gears...

Yep. And once again it looks to be nicely made.

We see you have posted a pic elsewhere asking the brand of this lever.

https://i.ibb.co/wh0qwJx/33.jpg

There is probably more vintage (and veteran) expertise here than anywhere else on the planet. !
Lets see if anyone can fathom what this brand may be - its pretty far gone.

SA were fond of putting their mark on their (handchange) levers.

Hi R, I've been a fan of this forum for several years, and I continue to be, but I need to try all possible alternatives to identify this unusual change.
The mechanism may even be a single piece, but the lever has a brand, so I believe it has been mass produced. It may not even be from an English bike, so I was even thinking of posting in the topic of European bikes ... What do you think?

Fair enough.

I think that posting in Euro bikes here will get about the same readers.
Can you beadblast the lever to see if the logo comes up any clearer. ?
It looks like a little rust and corrosion has muddied the waters.
This may merely damage it further, so know when to stop !

Does it say WINCO? If so, it's off a bike so rare I can't even find a photo of one. 1920-22 they say, but they didn't advertise in the Motor Cycle or exhibit at the Show.

Hi Paul,
The hand lever is a seperate piece. You can't be sure it is an original part of the whole mechanism. All that trademark identifies is the lever itself. It is not a good indication for who manufactured the rest.
I agree the change is well made and has all the indications of a commercial operation but I see it as an aftermarket accessory and probably nothing to do with any gearbox manufacturer. Eventually one day the information will just fall into your arms but I wouldn't let it distract me from getting the bike back on the road.

Cheers,

I will try to "clean" the lever a little more. See the new picture attached with a draw of what I can see (white line) and what I think I can see (blue line)
We would all like to find a "treasure" but that should not be the case :)

I very much appreciate the process of researching and discovering the history the story behind each piece.
I think the lever could be part of the change/kit because otherwise it wouldn't have a lever or it would have the original Sturmey Archer lever.

This bike had a different life... ehehe
