weight (W): is as they are shown, (some forks will have other parts attached and that's included in the weight)
axle to crown length (A/C): this is from the centre of the axle to front of the underside of the crown, so gives max clearance and will indicate whether it's close clearance or larger clearance. Use this also to estimate the brake length needed. Axle to braking surface is c. 311mm (based on 622mm bsd for 700c - use c. 315mm for 27" ) , bear in mind brake don't sit on the fork but in front so add a few mm. Also it's only a heuristic to say that the bsd is where the brake surface is.
steerer length (S): is given as 2 numbers denoted like this A/B, A is the whole length from end to crown and B is the amount of thread on the end of the steerer.
offset (O): (how far the axle sits in front of the steerer) I've estimated offset (rounded to nearest 5mm) by making a simple jig, so it's an estimate only (sometimes it's wrongly called "rake" - but that's a factor of tyre size and frame head angle as well)
(all measurements are done as accurately as i can, but may differ by a small percent depending how you measure, especially A/C and O )

W 762g A/C 350mm S 182/35mm O 35mm
old style ends (prob 531), there's a number on steerer that might help identify? - nice old steel headset fitted which is almost certainly a TDC continental (needs loose balls fitting). Fork has an old look to it, long sweep on the offset and nice long ends - they do fit the modern 9m axle as well as the older imperial axle
- please note this price includes the headset, (which seems to go for 50 to 75 on its own), I may split on request
