Inter clubman plunger tool box

Forums

My 1950 plunger Inter clubman came to me without a tool box and it’s something I’d like to fit for practical reasons. I have studied web photos but I’m not confident of how the box is fixed to a clubmans bike, particularly the lower fixing arrangement. Would someone be so kind as to post some pics of the mounting arrangements and the correct tool box type to help me track one down?

There are two lugs on the upper rear frame tube, presume one or both will be for the tool box attachment, but nothing immediately obvious on the lower rail with the exception of the footrest mounting which doesn’t seem to match up with the vertical tab bracket I can see on a few tool boxes offered for sale, though none of them have been advertised as Inter. All thoughts and advice much appreciated, and if anyone does have a suitable tool box please let me know.

cheers

... - 1952 plunger ES2 - is similar and only uses the top 2 fastenings. It seems very rigid with those. I have no lower mounting tab, although the toolbox came in a box of spares from an aution so can't verify it's of original pattern.

It did take a while to source mine and it was in pretty ropy condition.

....fits all plungers with the possibility the holes are drilled in different spots. I too found an orphan toolbox and needed to weld and redrill the upper mounting holes. Just the two, no lower mount.

It may not be relevant, but for a short while, WD16Hs were fitted with double steel pannier toolboxes and the lug for the lower toolbox mount on the chainstay was deleted...when production reverted to a conventional box, they used a "P" clip around the stay. Even with the brazed lug, there was a short spacer tube that was not shown in the spare parts lists, although the 2 3/8" length of the bolt specified in the lists makes it clear that there must have been a spacer.

Hi Bruce,

   Michael is correct, both plunger and rigid frames use the same box with the plunger ones fixed on the top only. The ones you have seen with the bottom bracket are for the rigid frame where the bottom frame tube runs close to the bottom of the box allowing a short bracket on the tube to join the one on the box. As there is no bottom support on the plunger type, it might be best to put a full length steel plate inside the top of the box to give more strength and support.

On both my plunger frame bikes I put a bolt and suitable spacer from the bottom of the toolbox through the mudguard to stop any vibration.

…for the advice, I think I know where to go with this now. Will see if I can pick one up and take it from there.

Cheers, Bruce
