I have just purchased an old tandem, but don't know the make or year. Can anyone help me to identify it. The frame is steel and it has a frame number of 452599. There are no decals fitted but I attach a photo of the front tube casting where a decal was probably fitted to indicate the make. The wheels/rims are 26" x 1.3/8" and the rear has a Dunlop Motorette tyre fitted (still holding air). The front handlebar has "Il Primo Milano" on it. The hubs/brakes are Sturmey Archer (Front has a number 10 5 6 on it)Tandem Picture 1 There are four sprockets on the back hub. The derailleur is a Benelux Super 60 The seats are marked Iscaselle. From what I have been able to look up on the derailleur, it suggests it could be 1950's or 1960's but that is all I have found. Many Thanks![Frame Number !Frame !Derailleur![Tandem 2 ]3

  • Check carefully on the head tube, the bottom bracket, et al for a serial number. Sometimes the serial number scheme gives a slight clue (though I don't know where you'd find a reference for that). Also, there are other sites on the web that are more into antique bikes than this site. Commented Sep 26, 2013 at 11:26

    There's a good chance it's a Claud Butler. (Check out retrobike.co.uk) Commented Sep 27, 2013 at 10:50
  • That's a gorgeous old-school tandem. What did you do with it in the end? Feel free to post an answer to your own question, and accept it by clicking the tick/checkmark.

Probably not a Claud Butler or a BSA, as the headbadge is the wrong shape.

The name on the handlebars and use of Benelux and Iscaselle suggests Italy (and Sturmey was big in hub brakes everywhere, so may not be British-made).


I'm pretty sure after looking at hundreds of headtube badges on Google images, that that is a Royal Enfield. I just bought a tandem that looks VERY similar but a ladyback model. It does not have a headtube badge though.
