That is very cool, a plain 306 decal, not a 306A.
I would like that and to find a plain 306 for the collection.
I find it strange the 306 was actually produced after the 306A was introduced and not the other way around. I mean why bother producing a manual only oiler saw? Did they really sell for that much less to be worth the extra expense of building them?
Just to be sure, I went out and checked mine..it's a 306A. Darn, thought I might have something rare! I've sold several of them and don't think I've ever seen a plain 306.
