Vintage 1940's Wolverine Adding Machine This listing is for a child's tin adding machine. It was manufactured by Wolverine Mfg. Co. It works fine and can add to a total sum of 9,999. These adding machines were manufactured from the 1940-1950's. What I have found about this adding machine it is model # 39, but not possitive. It is made of tin and has red, white & royal blue colors. It measures approx. 6 1/4"w x 9"l x 4 1/4"h. A few scratches and wear to machine and some fading check out the pictures I try to show any scruffs and scratches.
