i have what i suspect is a 1994 orange clockwork but the bb fitted to it by a previous owner appears to be the wrong length as the chain rings sit way to far out to be of any real use. I searched through the brochures on here but exact deetails of the width across the square tapers is missing. I dont suppose anyone here happens to know the info i require please?

If you look how many mm closer you want the chainset to the stay,
Take out the bb, go to LBS and ask for a bb with the axle projection that many mm shorter on the drive side.
Some chainsets have bb length posted online, but not all.
When we see this on a bike, it's usually the PO had fitted a different chainset onto the existing bb rather than they've fitted the wrong bb onto the chainset btw

Sadly I junked all my old Shimano catalogues many years ago but some are still available online in various locations. They were great for actually publishing all the tech specs so information can be had with some judicious googling and a part number, usually.
