Caper,
This is the back of a 1920's bevel back gangable switch box. The steel is not galvanized, just painted black. The loom knock outs (the bottom two are the most visible) were intended to be punched into the box with something like a tack hammer.
A cotton binder from a coil of Loom.
This is hard to read, even when I have it in my hands. This photo is color shifted a bit from yellow to red to enhance the actual yellow ink (for Gold) on the old yellow of the box board. The box reads: 1 Roll, No. 8 Size, Gold Bond, Pure Rubber, Splicing Tape, Northwestern Electric Equipment Co., Jobbers of Electrical Supplies, 174-78 E. Sixth St., St. Paul, Minn.
A scrap of foil, or sheet, solder. Paste flux on a splice and crumple the solder around it, then apply heat. Viola! Flowed solder joint.
