The McCulloch 10-10S Special Edition pictured in this post is listed on eBay (at the time of writing) with seller ‘chainsawfun’.
A few notable things about the 10-10S compared with earlier 10-10 models:
- The original 10-10 and 10-10 Automatic were 54 cc saws
- The 10-10S increased displacement to 57 cc and added electronic ignition
- The 10-10S is considered to be the final and strongest evolution of the 10-10 platform
- The special edition is probably a cosmetic/collector variant, not a unique engine or chassis version
Here are all the pictures, with a specs table at the end.
