Fullerphone details needed

[David Dunlop]

Just noticed the tool mounted on the strap of your Fullerphone. What is it? I have seen a lot of those straps, nearly always fastened to Signals equipment like RCU's, Fullerphones etc and wondered what the three small canvas loops and the small adjustable canvas strap secured. I think the strap has a YA number on it (YA 1532 or 1632) sometimes stamped in black. Don't think I have run across a maker code or date on any and some are completely blank. Both my Fullerphones have these straps. One has the YA stamp only and the other is blank. The small buckled straps on both have a reddish dipped end to keep it from fraying. May need to find a few more if them.
