Purchased one of these 25cc top hand saws recently. and I'm pleasantly surprised by the build quality. I was wondering if anyone has an idea about the lineage. Chineses saws are usually built from old Stihl or Husky dies, but I can't find any saw that looks like one of these. I can usually repair a chinese clone with off-the-shelf parts from Stihl or Husky but I'm scratching my head with this little top handle. I like the simple, old school throttlel/choke controls.
