Help please to identify my Tandem 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)
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

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).
