Hello Gary,
The Victor was made in three different design series, in two frame styles and with several different barrel/rib variations. The link to the chart shows a lot of different variations. The serial number is ML 75,604 Yours is probably marked "VICTOR" in the frame. Early Victor were marked "THE VICTOR" on the barrel. Yours is a 107 series Victor.

This can be used for anything from plinking to match shooting.
