Hello again!

at yesterday evening's leafing through my birthday present ( ) i found something interesting and I think i have solved some of the puzzles:
Peddled Scheme contractor for Stock buts was, among others, also the company E.J. Riley.
Citation from this Page:
".... The fateful year of 1914 saw the capital increased to 1120,000, but in August, the war started and the machines were turned over to war work, with Rifle Butts and Aeroplane Struts being made instead of billiard tables..."
So could i assume that my SMLE Butt was made by this company - E.J.R. Stamp??

The L&C (or L&G, L&O) on Buttplate - could that mean Linley & Co. ? Also a Peddled Scheme contractor?
