Vintage Albertson & Co. Sioux Valve Seat Reamer Grinder Set Sioux City Iowa. I got this set in a lot at an estate sale. I have no idea how to use it. The cutters are marked 192, 193, 194, 195, 196. The 195 is chipped as shown in the photos. Items look to be in great vintage condition. Items need to be cleaned up a bit. Original metal case latches as it should. ITEM SOLD AS SHOWN AS FOUND PLEASE ASK QUESWTIONS AND ASK FOR MORE PHOTOS IF NEEDED THANK YOU.
