208XXXD010  Oregon powermatch

Guessing 20" 058 but wonder what the D010 mount?

Found 20" 058 info.  D010

Note: PowerMatch & Pro Solid Nose Bars may be stamped with XXX, ZZZ or Other as they can have different noses installed on the body,
there by changing the part number.

In a few cases where two bars would have the same length in their part numbers but different drive-link counts, the letter Z will be used in the
bar-mount description to distinguish between them (K095 and Z095 for example).

I have a 2005 Oregon parts catalog that shows a D010 bar mount.  Used on Partner 550,650,1655, P-65, P-70,P-85, P-100, R-11, R-21, R-40, R-420, S-50, S-55, S-65 and a few other Partner saws. Similar to the D009 mount with 2 extra bar stud  holes. A mid 1980's Oregon catalog lists the mount as an H010.
