what's this doodad from GB?

I search ebay for GB items every now and then, being on the lookout for brake parts, wingnuts, a nice chrome stem, and of course the elusive handlebar end plugs.

Well, today's search turned up this doodad. The seller calls it "friction adjuster" but admits to knowing nothing about it. From the photos I can't even tell if it's one or two pieces of metal; maybe it's a wingnut threaded onto some other random thang?

Not sure, but they could be those special dropout wheel axle lock/retainer.

Is that cork in the lid? I see cork in old time water bottle caps. A wild guess but I like it.

Too bad the seller didn't day what size those actually are so that we might speculate what they'd thread into. Maybe they're really tiny and are alternative BB oiler caps!

I have the feeling it's not even directly related to a bicycle and the wingnut was just placed on that cap as decor. Or, "maybe it's something really cool I don't even know about".

Yeah, that's basically what I'm thinking, too.

Huh? Are there such things? I don't believe it. I, for one, know of no such things.

The cap looks very much like a rocker-box cap for a English motorcycle engine (BSA, early Triumph,??). So maybe some kind of cobble?

Definitely a cobble. The screw cap itself (and I'm guessing on size) appears to be a rocker box cap from a Honda motorcycle engine. Used on any number of Honda engines going back to the old CB72's and 77's in the mid '60's - part is still in production for a number of their 'play bike' motocrossers (not the serious competition stuff). We must sell a couple dozen of them annually at the shop. It probably the oldest single part Honda's had in continuous production.

Althernately, it could be an aftermarket (custom) valve adjustment cap for a 62-70 650cc Triumph vertical twin. The stock ones were simple, domed, and had an x-shaped groove cut in the front for a turning bar to be slipped in to unscrew it.

Not knowing the size, I can really decide which answer is the correct one, but the Honda has the better odds.

The other part appears to be a GB axle wingnut. The combination is cleverly photographed (the internal cork doesn't help) to hide any obvious method of attaching the two parts.

Well I guess this post is now preparing to merge with the " re-purposing bike parts" post from last week.......engage turn signal ( optional in NJ & NY ) and floor it.

+1 The first time I looked at it a fork cap came to mind, but I think everybody that said a valve rocker cover is correct. Super Modified.

People put random old stuff like that on ebay, but they almost never know what it is; so it's very hard to find it that way.

Do you have a photo of one? Any chance a spring from another type of brake will do the job?

How hard would it be to fabricate a spring? Get the right steel, bend it to shape, and heat treat it... seems to me you'd know how to do it much better than I, no?

I have a set of GB Courier brakes, and I have a bunch of random springs in a parts cabinet I picked up from a bike shop a while back. I'll check and see if I have anything that might work.

Drill a hole, use a bolt with threads to match an axle, hide under cork.
