You may want to check your info a little better before you make generalizations like this.

I think the "1" prefix refers to the new spring mounting rather than the old rubber ones.
MS340 rubber became MS341, same with MS360/361, MS440/441 and now the newly spring mounted MS380, the MS381.
The 380/381 is only available in countries without strict air control laws.
South Africa, Mexico, Australia and so on.
Please note the word "think" in my hypothesis.
You may want to check all the words in a sentence before you attempt a derogatory response. :jawdrop:
