This aluminum serial number plate is from a 1947 Unisaw, and is attached with screws. They are made of aluminum and measure 1' x 4' with rivet holes approximately 3-3/4' on center. Style 3 plates were introduced in late 1947. They are fairly common but are somewhat fragile and are often missing or in poor condition. They were used between early 1942 to sometime in 1944. Style 2C plates were made of 'oilboard' (dense coated cardboard) and measured 3/4' x 3' with rivet holes spaced the same as the first style plates. Style 2B plates were made of steel, appeared in 1942, and are quite rare. It is likely that the plate shown above originally had a red background. We have seen two other examples of a brass plate, one of which has red-painted background and the other has traces of red paint remaining. Style 2A plates were made of brass plate and are from late 1941 or early '42. Style 2 plates are from the World War II era, and are made from one of three materials: brass, steel or oilboard. This style was used beginning circa 1939-1940 to sometime in 1942 (probably early 1942), and then again from sometime in 1944 to late 1947. Style 1 plates were made of aluminum and measured 1/2' X 3' with rivet holes approximately 2 3/4' on center.
