I think they are pretty neat.. No defining stamps or marks outside of stem shifter 333 written on it. I searched the web and all I can come up with is that they are Shimano. But I thought Shimano stamped everything. I am just curious if there is any history to them, and what bikes they could have been used on and what years.
Looks like something off one of those rail/banana-seat hot-rod bikes of the 70's.
has it. It's a Shimano model L908 10 speed stem shifter from 1973.
