Probably what saw and whats the number on the driver 91??

Very likely, but we need more info to be sure.
91 & 72 on drivers, 2 diff chains/saws

3/8" low profile is very unlikely with those dl counts - that sounds like regular 3/8".
72dl means 20" (fitting many brands), 91 is the Stihl count for 28" (most others use 92 or 93).

Must be getting late (or would that be early?) for the Troll... :msp_tongue:
Those are Oregon chain designations. 91 is 3/8 low-pro and 72 is standard 3/8.

Yes, I misread the post, missed the "on the" part of it!
:msp_biggrin:And yes, early rather than late, and lots of beers......
cutters on both are 5/32 high, as opposed to 7/32 on "normal" 3/8...

The chain stamped 72 is standard 3/8 and uses a 7/32 file.
will get some pics up a little later... they are both 5/32...

First two pictures are of a well worn 3/8 chain. Second one sure looks like 3/8 Low Profile to me from those pictures.

Yes - as expected!
