1931 - 1934 Tandem id needed

[stevevw]

I have a 1931 to 1934 Tandem that I am getting ready for Anjou Velo vintage at the end of June. I have searched for a make that matches mine to no avail, so any ideas gratefully received. Sun, BSA, Triumph or Grubb?

The three speed gear is the first version of the Trivelox that was first sold in 1931 and was superseded to a different design the Model A by 1934 plus the rear dropouts are Trivelox horizontal rear facing. So that is what I am basing the age on.

Frame number on the stokers bottom bracket is like below
TH
N 228 NW

No markings on the steerer.

Thanks Mike.
And if you ever come across another green Bluemels please let me know. I had a stone go up in the front and broke it on my Paulus Quiros.

I have looked at the Frame number again and come to the conclusion that It could read DN22 8NW which is a Postcode near Worksop and seeing as it came from Warsop it probably is not a frame number after all. A bit of a disappointment not being able to find a frame number. The lugs look to be pretty generic for the era too, Now the frame is stripped down it is surprisingly light.

Could it be a Carlton, more digging to be done.

Carlon did make a few tandems, later than this I think.

I'll do m best to get a picture.

The earliest Carlton Catalogue I can find is 1937. This shows a Tandem and the Trivelox gear is listed as an extra at 42/- This would have been the type A gear by 1937 though.

Anyone have access to any earlier Carlton catalogues?

That is simply lovely, room for all the family! I'm wondering if you should rule out BSA because I've just identified my old boneshaker with about 75% certainty as an early 40's BSA and the fork crown is different to mine and the others like it. The angles on yours are much more relaxed which always points to early era, so I'd say yours is well in the 30's there. I've heard a lack of chromework suggests it's wartime period due to the lack of resources, but someone else would have to confirm that.

It's a 1930's dagger shifter on the SA, I think pre-'38 according to here: http://www.sturmey-archerheritage.com/f ... ew-291.pdf

SA hubs usually have a number stamped on them which corresponds to the date, e.g. 66 = 1966, but it's not always there and it's missing on my BSA.

The brake levers look to be correct for that era and are the same as mine.

Lack of chrome work is due to being over painted black at some point. the stem shows signs of being nickel plated rather than chrome as does the brake levers which are brass under the worn nickel.

The shifter is not a SA part it is Trivelox.
The rear hub is also Trivelox not certain on the front yet but could be British Hub Company, I will be able to see once I strip the paint off. SA hubs of this age do not have date codes on they do usually have a part code though which can be a good indicator to the age.
I agree about the fork crown. the crown is about the only difference on this set of pictures of a 30's BSA https://www.flickr.com/photos/26365547@ ... 5693325446

I am now thinking that Carlton is probably not correct either as in the 37 catalogue it says about fishtail and filed lugs which mine does not have.
