Displacement is the same for the farmsaw,P39, P41, P42 at 66cc. The P38 is around 57 or 58 cc's, if my memory serves me well. The farmsaw series were designed for more casual use such as around a farm and were built with plastic recoils instead of metal ones like the P41, P42. The P41,42 series were professional saws. Recoils are metal with metal internals rather than plastic like the farmsaws. Rings are usually thin on the P41,42 versus thick on the farmsaw. This was supposed to reduce friction and increase performance. Coils are different on the farmsaw and tended to give more problems than the P41,42 series. The P42 is just a newer model of the P41 with some internal modifications to increase durability. When Poulan took over from Pioneer the P41,42 series became a Poulan 405 and was the last of this series.
