Vintage Speedball Linoleum Cutters

This set is post-zip code days, but it looks very much like the 1960's. There are no dates on any of the box or the contents. It contains two handles, 6 blades and 2 sets of instructions. The handles are orange plastic. Everything seems to be without damage, except there is a bit of what looks like the backing of linoleum of two of the blades. I will be happy to email photos of the contents of the box. I need your zip code to calculate the postage.
