Curtis F&F ID help

[Del]

I've just come across a Curtis F&F  and bits but no idea what type it is (possibly a Curtis Pro?). Can any one ID it from these pics? (Sorry for the rubbish pics, took them with my phone in a hurry).

here's a couple of better pics, top tube is 18inces from centre of headtube to centre of seat tube. Serial number is on the bottom baracket tube and is 1083 49 which i guess is number 49 dated Oct 1983? Anyone tell me which model this is?
