[Toms306]

Tom get the tape measure out and confirm my mesurements in the description

Port Type Ø 4 mm
Cone Pitch 63°
Fitting Depth [mm] 25
Overall Length [mm] 99
Thread Size M 10x1
Spanner Size 10 mm

Gonna struggle measuring the cone pitch.

But I can measure the rest tomorow, it's at my Nans and Im at home atm.

I'm pretty sure it wasn't a 10mm spanner though, think it was 12mm as I remember it being an odd size.
