163-1 Years ago fuel delivery trucks didn't have any type of a pump to transfer the fuel from the truck to the farmer's storage tank. The fuel was moved in 5 gallon containers by hand. This indicator was mounted on the truck and each time a 5 gallon can was filled they advanced it one space to keep track of the gallons delivered.
163-2 This is a wire fence tighener, patent number 658335
163-3 This device is a fishinglureretriever for when thelureis snagged on a branch or rock underwater. The slot would be opened and the line would be slipped into the cylinder, the slot would then be closed. The retriever could then be lowered and raised along the line by a cord. If the weight of the retriever didn't dislodge thelure, the chains could be entangled with thelurehooks and help pull it out.

156-9 Someone emailed: "Attached is a photo of a solid brass, 12-inch gauge I recently found. It has a scale that is divided into tenths of an inch and is adjusted using a gear rack drive. There are no markings that would help to identify the gauge’s origin and the numbers are hand-stamped. Anyone have any ideas as to the intended use of this item? It probably originated in New England, since that is where it was found."

150-1. This is an instrument for taking water samples from varying depths in a body of water. A line from an anchor passes up through the "quick thread" fitting on the lower left and up through the lever mechanism. A test tube is placed in the tube (that looks like a gun barrel) facing down. The unit is lowered to the desired depth, air in the tube keeps water out. A small weight (called a messenger) is then sent down the line hitting the lever, unlocking the tube holder. It flips down allowing the test tube to fill with the sample water. It's then pulled up with the sample intact.
