This is an addendum to a "Parko" steamfitter's vise posted recently by
joe.striper on the big vise thread. It's believed to have been mfg. by the Athol Machine & Foundry Co. and really sparked my interest. Being a new to me vise, I decided to do a little vise investigation...go figure.
I couldn't find anything specifically on a "Parko" vise, so I went down the trail of the Athol Steamfitter vise no.1115, which became a much more fruitful search. First off, the comparison of the two vises showed their obvious similarities.
The Athol vise no.1115 was first introduced in 1935, as seen in the article below, as well as many other periodicals of that time. It continued to be offered in all of the Athol catalogs into the early 1960's.
According to a 1936 article, the vise was designed for railroad shops.

1936 Railway Locomotives and Cars-Volume 110-Page 507
Heavy Duty Steamfitters Vise
"The Athol Machine & Foundry Company, Athol, Mass., has recently developed a pipe vise especially adapted to meet the requirements of heavy-duty pipe fitting in railroad shops . This model, developed in consultation with engineers of a large Eastern firm of piping contractors. The base and jaws are extra-heavy semi-steel castings correctly proportioned to withstand the strains of steamfitters work.
Note that the front jaw is fixed, and the back jaw moves, a feature that allows long pieces of pipe to rest upon the bench. There is no need for blocking or special supports as is the case when a movable front jaw brings the pipe out beyond the edge of the bench."

This was all very interesting to me, but when I stumbled on a 1937
Air Conditioning Heating and Cooling article, things got even more interesting. At the end of the article, it stated that the vise was mfg. by the Athol Machine & Foundry Co. at
621 S. Kolmar Ave, Chicago IL.
What? That wasn't their address.
Well, it turns out that it was the address of the
Hannifin Mfg. Co., who in fact manufactured machine vises as well as many other items. It is this company that I believe not only was the mfg. of the very robust Athol Steamfitter's vise, but also the seldom seen "Parko" vise.
The history of American vises continues to amaze and enlighten me. Outside of the GarageJournal, I've found it's better for me to keep that to myself.
