Would appreciate any help on this. The first picture is from
ebay listed as a WDDO-007. The second picture is from Wexler's. Do you think the first pic (
ebay) is a
DDO or
Machine Doubling? I have a bunch of these to look through and don't want to be thrown off. I'm thinking the
ebay pic is
Machine Doubling because it looks shelf like but not sure. Would appreciate any comments. Thanks.
