Try the magic summoning formula...The first digit is the year of manufacture per Husqvarna standard for that era, not the first 2 digits. The next 2 digits are the week. However, your serial tag obviously doesn't follow the standard as there is no week 55. If you look inside the plastics of your saw, you can clearly see the date of manufacture is 87 (1987). That fits with the "8" on your serial tag (1988). Husqvarna couldn't put plastics manufactured in 1987 on a 1985 saw - obviously, but someone could have swapped out the plastics at some point in the last 35 years - who knows? The most definitive way to confirm the date of manufacture is to remove the fuel tank and look for the casting date on the underside of the crankcase, or check the manufacture date on the lobe of the crankshaft.
The 2 guys who might be able to shed some light on this mystery saw are Tor r and Sawtroll, but they both seem to have left the chainsaw forums in the last year. That's a shame as they hold a wealth of knowledge.

A "Tor R" doesn't show up in the current membership.
