I just listed this item on Ebay but as I am in Canada the item does not show up on Ebay.com as I have it listed as "local pick up only", it is on Ebay.ca. I am happy to to assist the buyer getting it shipped or delivered but Ebay is not friendly for big items. As described it is a nice unit from 1941. I has been used but it has been stored for 10 years and sadly the compound slide is missing but other than that it operates smoothly and is oiled and will run now or a great restoration of a working machine, have a look at the ad, questions are welcome, thanks for your interest.
