Thanks for the compliment! I do have way too much P37 webbing for sure. Some webbing collectors collect by maker, some by date and some by condition. I mostly collect by country of origin and try to avoid blanco if possible (I think it might be carcinogenic).
As for your question, I believe musketry order was intended for range practices and retained only the equipment necessary for those exercises. The 1934 Royal Naval Handbook of Field Training (courtesy of Karkee Web) describes Musketry, Drill and Fatigue Orders as follows...
I'm not sure if non-FB users can see this page or not, but here are some of the uniforms I put together with this webbing...
British & Commonwealth uniform
"Blanco made during the war contained carcinogenic materials and so today's re-enactors use blanco that comes in a liquid form. This can be applied with a brush but can be just as messy as the process was during the Second World War."
Whatever its just an opinion.
Actually collecting WWII British militaria can be hazardous to your health! The gas masks contain ASBESTOS, the compasses contain RADIUM, the blanco is CARCINOGENIC, and the mess tins have LEAD SOLDERING!
I'm amazed any of the tommies were healthy enough to fight with that kind of kit. lol
