Where did the badge go in the second pic? All absorbed by glare?
Looks original to me. There are some mid-year change saws I've seen in the 026/036 model line.
For example,
@Onan18 has a metal badge decomp 026 PRO, only one I'd ever seen.
036 Have that flat top cover. All MS360 are PRO and usually have more of a bubble top cover and only a rounded model spec badge on the recoil.
Late 036 and All MS360 have a bigger airfilter and matching AF cover with a lever and not the knob your saw has.
Your saw has the more desirable rear cover, at least to me. Your saw should have a non compensating carb and the smaller airfilter. You can put the factory metal mesh filter on that saw and the saw will perform better.
