Life Boat and Life Vest Makers and Sales Agents

It may seem like a piddly point, but if you were the guys who made life boats and life vests back in 1912, the sinking of Titanic meant your ship had come in.

Who were the major life boat and life vest makers back then?  How many more were bought in 1913 compared to 1912?  What happened to their stock on the stock market?
