Help identifying tandem frame I bought this frame in a state off eBay a fair few years ago and have recently got it working again. 

I would love to know what make or year it might be. There aren't that many his / her frames I've come across and hardly any with the same tube layout as this.

I only came across one serial number on the frame (top tube) but it was too pitted to make out and has been painted over since. The BB axles have Brampton stamped on them but that's about all I have to go on. Maybe some one knows more?
Your bike looks like a 1908 Humber Lady Red Tandem Original Vintage Bicycle. You can look up some pictures and it is very close. I doesn't look like anything has been changed from the original and the previous owners may have customized it a small amount (note the handlebar style) . If this is what your bike ends up being, it could be worth something. Hope this helps!
