Believe this was used with lead sleeves. Either to clean or ready for splicing, the inside and the outside of the sleeve. You could adjust the blades to be either inside or outside of the sleeve, then you would lock it to the inside of the sleeve, then turn the handle either clockwise or counter-clockwise, depending on if you were working on the inside or outside of the sleeve. Item is marked W.U., wooden box is marked and there is box with some spare blades in it that is also marked.
Trying to move this for a non-collector that contacted me. Had this at Springfield. Would like $300 for all. Can deliver to the National or possibly a couple of the Missouri Iowa shows. Shipping would be extra.
