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

I decided to ask the Google of the world and this is what it bestow upon me almost immediately;

Oh and it's made in Nottingham, so 73-82 according to the link I've found above.

A cycle manufactured in Nottingham, in the month of March of the year 1975, would feature the serial "ND5------."
For instance, the photo shown above, to the left, bears the serial "NL9------," indicating a machine made in August 1979, at the Nottingham factory. The example to the left is "WR0------," which would indicate Worksop manufacture in November of 1980 (and most likely a 1981 model due to the late month).

my point about it's not being anything special is that it's not worth spending a lots of money on in the near future.
