The Operating Saw Mill No. 464 would move logs by use of a vibrating conveyor into the building and finished timber would come out of the other side. Available from 1956 until 1960, this was a nicely done accessory that came with logs and lumber. There are various shades of GRAY base that this accessory is found in, which may be caused by oxidation or impurities in the plastic.

An identical saw mill was produced by MPC in the Modern Era under the No. 2301 from 1980 until 1984. However, this saw mill does not have the inscription "No. 464" on the windows.

Dimensions: 16-1/2 inches long, 6 inches wide, and 6 inches high.
