Got story on saw. His dad had bought new used to drop some what he called bigger trees on their property.  Must be why the 20" .325 set up was missing.  Saw has set since and dad has passed  I am guessing. He talked about him in past tense.  Saw was like new looking.

Only thing I found wrong was he brought me wrong bar 3/8LP and chain pitch 3/8LP.   Good thing I had .325 stuff on hand.   Showed him what he needed to get.

When did the PP4620AVX switch from 295. Just trying to get idea when it might have been bought first year.

How to Determine Size of Replacement Saw Chain

There are three basic measurements needed to determine the replacement chain. The first is the pitch, or the distance between drive lugs on the chain and it determines whether the chain will fit the sprocket. Most saws use 0.325", 3/8", or 0.404" pitch, with 1/4" less common. Most consumer saws use a type of 3/8" chain called "low profile". We call it Picco. A few older saws use 1/2" pitch chain. The second is the gauge, or the thickness of the drive lugs. 0.050" (1.3 mm) and 0.058" (1.6 mm) are most common, 0.043" (1.1 mm) and 0.063" (1.5mm) less common. Pitch and gauge together determine the size of chain. Length is determined by counting the number of drive links, also called drive lugs.
