Funny business this gauge thing - over here Stihl offer .058 only in .325, and .063 only in 3/8".
Husky and Jred is all .058 in both .325 and 3/8", except Narrow Kerf .325.
Scandy 14
FYI, "Stihl" puts all the info you need right on the bar. As you can see in this bar that its a 3/8 pitch 90 cm or 36" 1.3mm or .050 gauge with 114 drive links,,,,,, for guys like me, they even drew pictures!
