What you describe is exactly what came with my '71 Commando-I'd like to find another bag with tools as someone had sticky fingers!That pictured one is much nicer than the original was in '72. It looks like more of a bag than a tool roll. Mine had a black naugahyde roll with a shoestring-like tie. No logo. Fell apart quickly. The other original toolkit I have is in a plain white cloth roll. I suspect it is earlier than '71. Both have compartments to slip the tools into, then the flap is closed and it is roiled up and tied.
You have one of the rarest of Commando original survivors. My 72 750 and 73 850 had the cheesier units as others have described. They never lasted long. All of my other Commandos have been purchased long after the original tool bags had bought the farm. Old Britts has good photosI have a brand new OEM tool bag, never used. It is still in the plastic bag it was sent in.

I have the original 70 tool bag ,with the strap. Tools seem useless unless in an emergency , though poorly formed/cast.
