"...pearl handled two guns..." Ivory.
"...Looks like these people had the same idea..." There's tons of that kind of stuff around. SCA events swarm with 'em. I remember seeing plastic Roman armour as a kid. Had a plastic Roman sword myself.
Buddy of mine, in the SCA, made a safe sword for his son, pre-schooler,3ish, at the time. Was fine until the kid whacked another kid with a stick.
