Title: Where does this go?
Post by: Steverat on 28.02. 2019 08:54

It’s part of a 1951 plunger A10 but I can’t remember where and I’ve nearly finished the rebuild. Any ideas?

I can't place it. Might it be for the toolbox?

Homemade brake pedal stop?

I've recently finished stripping an entire 1954 A10 plunger and I definitely haven't come across that bit... so don't worry?  ;)

 Looks like a stubby holder-holder

Maybe the horn was mounted on it.

With the corner having a radius it looks like it was made from a piece of angle so i doubt it is original.

It feels like a properly finished part to me, the radii are all smooth and symmetrical, not hand filed.

Does it have something to do with anchoring the fwd  end of the rear mudguard to the frame ?

There are two struts for that

it looks like one hole is elongated --- chain guard or something that needs a bit of lining up *dunno2* my brake light switch bracket has one similar but I made it that way

Hi All,
It used to be a "standard" practical joke to drop a random part or two that "looked right" into the parts boxes
when some poor bugger was rebuilding something complicated,  *eek*
A likely looking shim, odd looking bolt or screw could and would drive the victim nuts  *conf2* *conf2*
and often lead to  *fight* *fight*

I think John has got the answer!! ;)

Looks like it was custom made from a piece of angle iron due to the radius inside the bend and the sharp outside corner. If it was made in the factory it would probably be a piece of bent flat which would look quite different.
The holes are different sizes too which may give a clue.

I'm building a 51 Plunger and it is definitely, I think, NOT a part for that bike.

If one of the holes is a nice fit on the shok bolt then most likely it was a bracket for fitting a rack or pannier frame.
Remember peple used to ride these things for transport so had to be able to carry things like a slide rule & note pad.

It used to support your wallet - before you bought all those spares .....

I found a photo of the frame when it arrived and the part was on the top of the near side plunger mount at the point where the lifting handle attaches. God knows what it supported. Probably a carrier which had disappeared. Thanks for the head scratching.

When you inhabit the rarified world of "catalogue correct " bikes it is some tims difficult to get your ead arond thawhen tese were daily transport people put non standard things on them.

Every BSA I have ever owned save the WM20 & WD B40 had a gear sack fitted and usually a frame for throw overs as well.
