If the forks on there are original, (they look like they are), drop them out from the frame and you will probably find a date on there. Should say
Taiwan-tange-92 thats if its that date, I reckon it is. Hope this is some help.
I had a 91 Conquest Hydrotech Comp, all the 1990/1991 bikes were a bit garish. That looks like a later 1992 model. The earlier models used Saracen own brand stems, that looks like a Zoom which were later than the 1991 range of bikes.
