Just to clarify, although I can criticise Freemasonry till the cows come home, having been a member since my student days, that badge has no masonic significance whatsoever, and anyone wearing it in a lodge would be asked by someone who divined its meaning to leave on the spot. I don't know how far you are going back, but certainly 50 years ago you would find men who were members of many organisations simultaneously. Thus it was not uncommon to find a man who was a mason, buffalo, round table/rotary, as well as other smaller "benevolent" societies who have disappeared off the radar since.
