As a general rule most switch keys were made of brass but some were of steel as shown here. I initially was told due to WW2 and brass being in short supply this was made during that timeframe but I recently learned this key dates to around WW1. Also some key manufacturers had a choice of keys being ordered either from steel or brass. Looking at the stamping it’s not hard to determine how the Missouri Pacific got the nickname ‘the mop’.

Mike Adams was one who indicated that at least some of the steel keys dated to World War II. That’s a nice example. The MoP designation is apparent on the key, but it was also most apparent in the early reporting marks on the side of boxcars.
