Information about an old frame I'm looking for information about this frame- it's my trusty touring bike, and I've been gradually upgrading it - next up is to convert to 700c and a modern chainset (probably sora to keep costs down)

The frame is a Falcon, and has a decal saying 'falcon' on it, but I can't find any information about falcons anywhere - no mention on Sheldon Brown of a falcon model, and scant information on Google.  

The frame is steel - 25 inch, lugged. It is pretty much the only original part of the bike!  It was originally a 10speed, down tube shifters, rear indexed, front friction.

So my questions: 

Can anyone give me an approximate date for the frame?  

Can anyone point me in the direction of a resource about falcons?

Are they a well known brand?  

I'm thinking of getting the frame resprayed - is there anything I should bear in mind?
