She is a Raleigh Romana built sometime between 1989 and 1992. She would have cost approximately £160 ($305) new.

Raleigh only used the mixte frame on two models - the Romana and the Impulse. Both were sports bikes.

I got the info from a chap on the Raleigh forum. There's no facility on there to put pics so I e-mailed him the pics and he came back with that info.

Nice to know what model she is and her approximate age
