Lightly used? Maybe, but not 'lightly' cleaned anytime recently. Myself, I'd never let my saws degrade to that point and I'd never post up a picture of them in that condition on a public viewed forum for all to see. You post a picture like that, you can fully expect negative comments, the way it works. I don't post pictures as a rule on any site and so you can take me on my word that none of my saws look like that, even my 40+ year old Stihl 028 WB. The paint might be faded from decades of use and it does wear a different bar as the old one wore out long ago, but filthy, no way.
Far as the non ferrous copper plates are concerned, all non ferrous metals (aluminum. copper, brass and alloys, all of them are prone to cracking as vibration will work harden them and while the do conduct heat well, however the negatives outweigh the positives in that particular application and I've never seen that application before, anywhere.
Far as my 'kit' is concerned, when I'm out cutting storm damage which is what I primarily do as our property is heavily treed with mostly maples and oaks and a smattering of long and short needled pines, my 'kit consists of the 'scrench, a quart non dairy creamer (empty of creamer of course bottle) filled with bar oil and another one filled with canned gas, both suitably marked with paint marker so I don't mix them up and the creamer bottles have nice, securely fitting snap lids so the don't leak plus it's much easier to fill the saw and not use a gas can or gallon bottle of bar oil which is always messy anyway, a spare loop of sharpened chain and my ever present chip brush which I always use to remove any swarf or sawdust from around the fuel and oil filler caps prior to opening them. In fact, I've NEVER replaced any in tank fuel or bar oil filters on any of my saws and that includes my 40+ year old 028 which I use a lot. If I see pitch building on the heel of the cutter teeth, I always switch loops and when I do, I always flip the bar over as well and I'll take an old expired credit card and run it down between the bar rails to remove any accumulated swarf as well. All my bars have greaseable roller noses as well and they get greased every time I put the saws away after using them, preceded by blowing them off with compressed air prior to putting them away.
My mileage may vary from others but I'm happy with my regimen and it works fine for me. You won't find any crud buildup on any of my saws, ever and of course I only run canned gas and quality bar oil. Interestingly, the 40+ year old Stihl 028 WB I own still has the original spark plug in it as do my other saws I use regularly. The air filters get cleaned often and I remove the clutch cover and clean under that as well often, however. I really like the empty and refilled non dairy creamer bottles because they have snap caps and make refueling and adding bar oil much easier and less messy. Kind of anal about keeping them clean and ready for the next time I need them and of course they live in my climate controlled machine shop with humidity controlled at 50% and temperature stabilized at 70 degrees, always but that is more for the precision machine tools I have and not the saws. Stabilized and consistent temperature as well as humidity are important when it comes to precision machine tools and precision measurement. tools. The saws just reside in that controlled environment.
Even my 2 shelf queens, the 090 and the 075 that I don't ever use are clean and well kept and basically devoid of paint chips on the cases and bars. Bought them new and even over 40 years ago, neither were a cheap date.
That all fits quite nicely in a small wooden open top container I carry with me when I'm out cutting storm damaged limbs.
