Please thoroughly inspect the supplied product photos, read each product description carefully (any identified defects will be disclosed here), and asked questions if you're unsure about something before purchase. The tools I am selling are those that belonged to my late husband. Please research these items yourself as I don't know anything about these tools apart from knowing their condition prior to sale and have taken photos and will point out defects where I find them.
