Thanks David,
I purchased Volume 1 of your book "Tommy" from you in about 2002

. Great shot of the Carrying harness, can't say I've seen anything like it before.
I did see the firing pins on your website but until I find the ball end, I'm not sure if I need one. Still tempting, but I'm not sure which version we used.
I have no idea what this was used for

but I picked up this piece of webbing up a few years ago, marked F^L but no date. It has a small pad to protect the wearers back as well as what feels like a hard board sewn into the lower area below this.
