[1] NAMEPLATES



There are differences in the name plates on the old and new machines.

The name plates can bear a variety of company names :

... earlier machines are marked "CLARKSON (ENGINEERS) LIMITED".
... later machines are marked "Clarkson International Tools Limited".
... some recent machines are marked "CLARKSON MACHINE TOOLS" (see gallery 2).
... some recent machines are marked "March" (see Lot 186 below).

The 12 x 6 is also shown in metric on the newer machines.
The horizontal line either side of 'CLARKSON' is not present on the newer nameplates.
The word Clarkson is in lower case on the Clarkson International Tools Ltd nameplates.
The word Clarkson is in lower case on the Clarkson Machine Tools name plates.

[2] DATING YOUR MACHINE



These bits of information may help date your machine:

A reference to a lawsuit case "Clarkson International Tools Ltd v Short" looks to be dated February 1973.
An article in The Edinburgh Gazette mentions the name 'Clarkson International Tools Ltd' on 16th March 1973.
If your machine nameplate has Clarkson (Engineers) Ltd on it then it is earlier than 1973.
adendum: I have since come across a 1971 Operators Handbook that has the 'Clarkson International Tools Limited' company name printed on the inside. If your machine nameplate has Clarkson (Engineers) Ltd then it is sometime earlier than 1971.

The Handbooks dated April 1962 3rd Edition, March 1966 4th Edition, and March 1971 6th Edition, show a few pictures of some Clarksons with their serial numbers, namely 295 and 1500. So if your serial number is lower than 1500 then it was made before April 1962. If your machine is 295 or 1500 then it is famous as it is in the Operators Handbooks.
All this logic could be flawed if Clarkson have not issued the machines with consequetive serial numbers.

The "Clarkson Machine Tool" company was incorporated in 1991. So, at a rough guess, any machines bearing the name "Clarkson Machine Tools" were made/sold after 1991.

In Gallery 8, on 08-04-15 there is a machine, numbered 8088. This was for sale on ebay, located in Beccles. The seller stated that the machine was purchased by his father in 1964 for 149 pounds. I have no reason to believe that this is incorrect. So, 8088 can be tied to 1964.

I purchased my machine from a University. They told me that the machine was originally purchased in 1965 for 150 pounds, although I cannot verify that date. My machine number is 9866.

I think CLARKSON (ENGINEERS) LTD became Clarkson International Tools Limited at around serial number 11645 to 11672
