Welcome to Tool Talk from Wisconsin. Very nice tools. Thanks for posting.
The big combination pipe and nut wrench is a Bemis & Call. This particular one is the long nut version. The long nut was supposed to protect the threads. Below is a photo of the short nut version.
Here is what Alloy Artifacts says about the company history.
Bemis & Call was an early maker of tools and hardware dating back to an 1844 partnership between Stephen C. Bemis and Amos Call. The company produced a variety of tools including pipe wrenches, monkey wrenches, and other adjustable wrenches, and was especially well known for their S-shaped adjustable wrenches.
The line of S-shaped adjustable wrenches was introduced in 1894 and proved to be very popular. The sliding jaw design was very similar to the 1857 E.J. Worcester patent #17,531, with a slotted jaw running in a rectangular keyed passageway.
In 1928 Bemis & Call acquired the rights to the wrench designs of the Coes Wrench Company, a well-known maker of adjustable wrenches operating in Worcester, Massachusetts. In 1939 B&C was acquired by Billings & Spencer, which continued production of the B&C (and Coes) wrench models for some years thereafter. (See our article on Billings & Spencer for more information.)
