As far as I can tell, a MASONS’ Drag Saw and Cocks’ Combs were listed as far back as 1897 and probably before, but I must assume that you know what these tools were for, because I certainly do not!!
The 1897 information is below:
The 1909 listings [as before] show a change of item numbers:
These items were not listed [ along with many tools post WW1] after the war in 1921 but re-appear in the 1928 Catalogue:
The 1938 Lists the same tools at the same prices as the 1921 Catalogue..
But the 1959 Catalogue only lists this:
The last listing of these tools, that I can find, is in the Price List of November 1963
Here you can see a good Masons’ Drag, but I suspect that the ‘Combs‘ are now few and far between.
