Dunlap Box End Ratchet

[kcmap]

I purchsed this little box end ratchet at a sale the other day. Markings are Dunlap, Made in USA, Pat. =APP, 1/4 by 5/16, stamped on both sides.

Any idea as to who made these, when, and other thoughts?

Thanks,
KCMAP

my guess would be made by Parker:

Parker / Parker Mfg. Co., Worcester, MA / est. 1901 / patent 2058107 Oct 20 1936 & RE20252 Jan 26 1937 Dwight E. Priest & 2574676 Nov 13 1951 & RE24465 Apr 29 1958 Glenn J. Waterbury & 3181181 May 4 1965 John Z. Buckley & 3480055 Nov 25 1969 Gabriel M. La Pointe & 3742788 Jul 3 1973 Edward D. Priest / https://www.garagejournal.com/forum/showthread.php?t=427314 / https://www.garagejournal.com/forum/showthread.php?p=6206429#post6206429 / https://progress-is-fine.blogspot.com/2015/11/vanished-tool-brands-parker-line.html / https://mycompanies.fandom.com/wiki/Parker_Wire_Goods_Company /

but that's just a wild guess.

Don't know who made it, but I can tell you that two rivet design is deliberately cheaper than the common four rivet design. Please forgive me if you already knew that.

I think the Dunlap name stopped in the early/mid 60s?

Pretty much done by 1960.
