This is a steel body TTRR (Toledo Terminal Railroad) switch lock with chain, made by Adlake. There is no key.
The Toledo Terminal was a very short line in ....Toledo, Ohio. TT functioned basically as a switching railroad for other lines, with tracks right around the city of Toledo and not going beyond the city. The line's very short length meant few switch locks were needed, making this a scarce lock.
The padlock body is heavy steel, about 3-1/2" high, total weight about 14 ounces. The drop (keyhole cover) has the maker's name- Adlake- in raised letters. The date stamp on the back is 1978. The backside of the lock body is stamped "TTRR" and there is also a patent number stamp that dates back to the 1930s. The shackle is nickel-plated steel. Nothing is stamped on the back side of the shackle. This padlock does come with what appears to be an original chain, but there is no key.
This lock came from a small central Florida collection..
CONDITION- The steel body is reasonably clean, especially the back side. The drop spring is still strong. The front has some very light areas of discoloration,surface rust. The lock has NOT been cleaned, but certainly could be. The chain is still quite smooth, little rust. Because of weight I cannot ship this first class package mail but must send it priority mail; postage is offered at cost..
