Vintage sledgehammer ( RAILROAD?) with many interesting marks & stamps in metal head. “ 2-02 “ “RGP” and cool symbol that looks like a triangle over a Y with a line under the Y. The weight of the hammer may been stamped as well,  “4 1/2“ pounds? I have weighed it and it weights 4 lbs 13.8 oz. 

Really cool piece that would be nice to put on the shelf with your other tools in your collection. No international shipping. Shipping and handling to be determined at date of sale.
