Furbis: what would you like to know? Holland's was one of the finest vise manufactures of the early 20th century. that vise is a bolt through the bench swivel vise that might be early 1900's. it looks in pretty decent shape, but it is missing it's pipe jaws. not really a collectable, but a vise worth having.
don't spend more than a benjamin and you should be ok for value.
anything specific more you'd like to know just ask and if i don't know maybe another vise guy will.
here's my Reed 31 that is a very close US example and maybe as close to the same as a Holland's vise as you'll get.
