Here is a steel switch lock with original chain but no key, from the PRR (PENNSYLVANIA) Railroad. In the first half of the 20th Century it was the largest railroad in America. It still holds the record for the longest period pf paying dividends of any American company- over 100 years. At one point it was the largest publicly traded corporation in the USA, and its budget was larger than the budget of the United States. Wow. Times changed, and in 1969 it joined with the New York Central to form the Penn Central RR- and 2 years later declared bankruptcy. The combined line ended in 1976..
This padlock was made by Slaymaker, whose name is in raised letters on the keyhole drop arm along with the raised letters PRR. There are no other letters on the lock. It is just under 4" high and weighs almost one pound. Slaymaker locks are less common than the Adlakes.
CONDITION- Good.. The steel body has darkened but has little rust and it is surface, not deep.. The chain has a light coat coating of rust..
