They gave me an idea of what screw to look for the front band but I'm still at a loss for the screw that attaches the middle band and how the brass pins hold down the upper handguard. I'll have to take a closer look at my No1 to see how the brass pins work on it. Obviousy whatever the pins run through under the handguard, I don't have. Thanks for the link, saw it before but just realized it had a large photo collection.
