That's one of the 2 designs of chainbrake/handguard the 610 had.I think its the later version,I dont see it as often as the more common one like my old beast had,it looks more like more 'modern' ones pretty much....
*sniff*I miss the old beast now....It sat under bench for 11 years,filled the tank with fresh fuel,it fired right up.Sold it along with NOS 20" factory bar & NOS air filter still in the bag March 2011. I'll get another one someday,lots of them still out there.It was loud & heavy but pulled a 24" b/c with authority.
I was over my dad's getting the splitter the other day, and saw the old McCulloch sitting on his table saw. Thought he had gotten rid of it a long time ago. Maybe it just needs some parts to get it going. Might see if I can fix it for poops and giggles.
