An early 10mm 044 will sell for around $700- to $1000- Aud....A quick look on ebay finds a Meteor piston & Caber rings for $91-I like your choice there Scallwag but as much as I want to go for it , the cost of the genuine Sithl piston makes the saw not worthy to repair.
versus genuine Stihl for $125-. ....Wouldn't it be worth the extra $34- to rebuild your saw with genuine parts?
