Anybody know what this is?

[PT1989]

Tidying up/replacing clocks, no idea where/when I picked this one up, but it's quite small & neat, only goes to 60 so it'll do for the little Honda.

Went to fit it, and it doesn't fit! I then realised I've only ever changed speedos/cables on Honda bikes, and they've always been the same connection, which I just assumed to be a universal thing?

This one seems to be a miniature version of what I'm used to, does anyone know what it is? Has the same screw on design, but smaller, and the same square hole for the cable, but smaller.
Can I find a cheap adapter or am I better off just looking for another cheap speedo?

Added pics, for what they're worth
Last pic shows the front just Incase it's not a generic thing and somebody recognises it

Looks like an old smiths clock, but it isn't stamped. Lawn mower perhaps?

From an old car or a boat perhaps. Some old boats used on inland waterways had MPH instead of knots on the dial.

It's off an export model simson S51.


You will notice the euro-style 1 on the back of the clock with no underscore and the use of a comma instead of a decimal point.

Nice one guys! Thought it'd be too plain for anyone to recognise it. So does anybody know if/how I can use it on an old Honda, as it seems to be a mini connector on the back

[stinkwheel]

You'd need a speedo cable with a honda speedo drive fitting at one end and a simson clock fitting at the other.

Then keep your fingers crossed that they both use the same gear ratios in their speedos.

In other words, do-able but may be tricky and possibly quite inaccurate.

If you are very lucky, Simson might use the same speedo drive fitting as honda in which case you could use a simson speedo cable.

Almost certainly cheaper and easier to just use a honda speedo.

Unfortunately I suspected that might be the answer. It's a shame because I quite like this one, and already have it. But that's more effort than it's worth, so I guess it's keep an eye on fleabay for a cheapo Honda speedo. Thanks for the help anyway

I know the mz speedo mate is square cut, so presume the Simson one is. The honda speedo cable might just fit in it as a guess, i think they're roughly the same size. Which leaves merely the issue of ratio. Get back to us!
