OK, I kind of like these "what is it" threads lately and I've had these things setting around in my barn for years. I could never really figure out what they were used for and I think I found them in the wreckage of an old house.
I figure I'm missing some pieces, but maybe someone can recognize these parts.

Thanks,
Dennis
