Wanted: Park hcw-11 tool

The bottom bracket was a square taper, but** the type with the thread attached to the end** so the crank would have to be bolted on, if you know what I mean.
Got the frame for free the other day so am trying to build it up as a runabout for a while.

That's very similar to an older Raleigh then. I would try the WD40 then hammer and screwdriver method. Best bet being it unscrews Clockwise (opposite to the left cup). Don't worry about damaging the cup, it should go in the bin anyway. Replace it with a £18 Shimano cartridge unit.
