Is there anyone out there who is familiar with this product or company? A hanger used to connect a 4x12 to a GLB in an early variant of a panelized roof system, potentially as early as the 1950s.

The 50's was certainly before my time as a Structural Engineer. But, through the 60's and 70's there were a whole bunch of small industrial firms trying to get a slice of that wood connections pie. Simpson and USP, now part of MiTek, finally ran them all out of business. That industry with catalogs of std. parts was just coming into its own as something we could spec./buy, as opposed to having some small shop make 30 of some part which was our own design. I would talk with some of the older GlueLam outfits in your area, they were doing a lot of their own design at that time, both the beams and columns, etc. and the hardware they needed. They will probably have some idea of material grades and design stds. of that era; probably just AISC, common sense engineering design and A7 or later A36 stl. or some thin pl./sheet or bar stock spec. I did a bunch of that work for a local GlueLam outfit during the late 60's and early 70's.

All I found was a reference to a company that used to make Bowstring trusses.
I think dhengr is probably correct. That was the company that manufactured these connections. But, very little info is available for what they provided. I'm sistering an LVL to the existing purlin and was hoping to save my client a little money by relying on the hanger connection to transfer shear for both original purlin and LVL. But, now I think I'll give in and just provide a shear connection for the sistered LVL itself.
