I'm new to the forum but I just picked up a sweet, like new FM62 SCE T/R electric/acoustic mandolin. I've done my homework on the instrument but have found little information on the forum beyond an errant comment or two. Can anyone here tell me what the T/R stands for and anything about the serial numbers. I am certain that this is a post lawsuit mando built in Korea but I'd like more info like when it was made.
