Can you help to identify these frames, bikes or parts?

My Concorde Colombo lo pro is made from SLX and has a 26.6mm seatpost. Don't know if this is weird or not. Can be seen here

Hey mate, sorry that it took me a while to reply!

The lugs look to be the same as mine, as does the bottom bracket. But my dropouts are ultech (assume other mid-end 80s concordes used these, but these definitely vary) and my brake bridge looks like this (which I've seen on many other concordes, but couldn't say if they all looked like this!): http://farm5.static.flickr.com/4033/4614979533_db03b9e9bb_m.jpg

I've seen yours before, but can't recall where. Maybe a non-butterfly gazelle bridge? Curious and curiouser...
