It isn't that new. I am thinking a 450 or something in that line. The high top for the air filter marks this type of saw. Maybe 510/520? It has the Partner influenced handle design. I gotta take some new J-Red pics of what I got. Maybe, I will have some time today.
Looks like a 490 to me. The 450 and 510 line of saws have the brake handle that connects on both sides of the saw.
