Ahh! At last I've accessed the album site.
Here are the photos:

General view with tool in rearward position

Side view showing stock support centre and the guide rails – nearest guide rail is also the taper former

Front view with the guide rails in the forward position. The stock support centre sits just behind the rollers.

A front view showing the spring loaded plunger of the swivelling tool block sitting just to the right of the small guide rail housing.

Side view of the tool in the forward position. This is the start position and as the tool is advanced the centre moves back and the swivel tool block produces the taper.
Here is the Recessing tool:-

Front view showing tool in position and rack of the tool slide protruding to the right

Retraction and advance slide stops – I wasn't very good at neat stamping!

Side view showing tool clamp screw – tool is 5/16th bushed into a 3/8th hole.

Rear view showing the actuator lever and rear of the pinion.
