Here’s a great Husqvarna A100 example, this time from Tim Hunt’s collection.
We shared another one a year or two back, which was then listed on eBay for around USD $5000!
This 100cc model was introduced in 1962 (some say 1965), but there isn’t a huge amount of info out there about them.
The following are pictures of Tim’s A100 Chainsaw (serial 105043), which I took when visiting in 2025.
