British War establishments from early in the war

Hello. I'm looking for British infantry war establishments (Nowadays called TOEs or Tables of organisation and equipment) from early in the war. Specifically "An Infantry (Rifle) Battalion" from the 6th April 1936, "An Infantry Battalion (Higher Establishment)" from 10th of April 1940 and "An Infantry Battalion (Higher Establishment)" from 4th June 1941.

The earliest I could find online was from 1942 at War Establishments

Are these available for free online anywhere? Thanks in advance!
