↓ This nicely modified Clarkson belongs to Bernie on the Tool Grinding forum.
Serial Number = 13014
This has a modified motor bracket to relocate the motor, a new height adjusting screw with graduated dial and thrust races, a taper pin to align the swivel table, taper pins to align the spindle head (if dismantled), and a paint job.
The new motor position makes the machine more compact.

↓ Taper reaming the Spindle housing to make sure it goes back and stays aligned in the horizontal position.

↓ A very interesting picture of the dismantled castings.
These have had their rough cast surfaces and moulding sand cleaned out and hand ground to allow full movement of the new stud and height screw assembly. missing image

↓ The old and new height adjusting screws for raising and lowering the head.
Note the cad drawing.
The new top assembly incorporates 2 1/2" thrust races dust sealed, and a graduated dial.
The new assembly thread is M16 x 1.75 to get 125 thous on the graduated dial to correspond with the actual head movement.
My favourite picture. Very nice.

↓ This Clarkson belongs to BillyBobs60 on metalworking.piczo.com.
He's done a few mods and repairs. Looks like the table has been reground\milled\polished and he's added a graduated dial (and maybe a new feed screw and nut?).

↓ This one was given to a group of model engineers.
It has the Drill Point Lead & Tap Grinding Attachment (for the Mk2 and Mk3?).
It has the 6 jaw! The rack lever knob is missing.
They got it for free. Lucky sods.

↓ (10-10-07) Lot 82, the last bid was 20 pounds. The reserve had been met! Thrupp, King Sturge Auction.
There were 8 bids, finishing at 20 pounds.
Looks like it is set up to cut.
There are only 3 gib adjusting screws, not the usual 4?
The end of the handle is broken off.

↓ This is an image of a brand new Clarkson Mark1 off the MachineSpares website.
The pedestal and table feed screw handle is different. The light is modern. It has certainly changed.
