Forgan's Maxmo putter was first offered in 1928 and built for "Maximum-Momentum"!  It was designed to redirect a ball mis-hit on either the toe or heel back towards the hole—and to give the otherwise mis-hit (and therefore) weak putt more momentum than it would otherwise have had.  To accomplish these things, the clubface has a concave curve heel to toe and there are lead weights under the brass plate on the heel and toe of the sole. 

In theory, a ball struck on the toe of a RH putter would be redirected a touch to the left to correct for what would normally be a miss to the right of the hole. The lead weight under the toe would add back the distance lost with such a mis-hit.  Again, that was the theory. For more on the Maxmo putter, see TCA2 v1 p303

Nice club with a 34 1/2" shaft and original leather wrap grip.
