I just picked up two 50 pound power hammers one is a LITTLE GIANT and the other one says THE MAYOR Excited to get these things going I was hoping I could learn the history on these, the little giant I can read the serial number its 4154 The other one I cannot find the serial number. Up until now I’ve been using a hammer an Annville and a hydraulic press, I am new to the power hammer game, I see some people referring to someone named Sid and that he may able to dig up the history with a nice email asking if he could do so. Excited to get my hands dirty. Any positive input is welcome, Thank you all
