Just posted some more photos tonight:

290. a "spark gap". Used in old phone lines and antenna leads. One
terminal was attach to a ground rod and the outside line and the feed
into the building were attached to the other terminal. If lightning hit
the the antenna or phone line, the surge would jump the gap and go to
ground instead of into the building.

291. An eraser shield

293. A hanger for drying leaf tobacco

294. A tool for installing/removing fittings on cast iron radiators

295. a corrugated staple for butt joining two pieces of wood
