I'm not sure the age of this Proto clamp, as I found it in an old barn covered in grime and muck. But she cleaned up real nice, and continues to serve her intended purpose. While marked "Proto," some believe she may have been made by Wilton for Proto.
Opening: 3”
Depth: 2”
Weight: 1 lb 15 oz
Plomb tools changed their name to PROTO in 1948, so it has to be more recent than that. That's about the best I can do. Perhaps someone else may be able to narrow it down.
