Here's the extended tool history with some images of the various models. Here's the FAQ history with more images and the age chart.teamtj wrote:How do I know if I have a 500, 510, or 520?
The 500 had an 18" table with an art deco- looking fence. The table is not ribbed. The crank to raise and lower the table is a singe, red handle. The color will be green, brown or dark gray from the factory.
The 505 had a larger table that is ribbed but no connecting tubes and floating tables. The table crank is a wheel.
The 510 has the 505 table with connecting tubes and floating tables that extends the effective surface area of the saw and the tubes have legs at one end that reach to the floor. All table cranks after this are wheels.
The 520 uses the same tube table system but employs the "Pro Fence" system that has a beefier rip fence and fence rails that are large and square.
