What you are not showing in the pics is the drive tang. Is there a number on the drive tang. Lift the chain out of the rail and see. Some chains have em and some don't but a number would go a long way in identifying the chain with a husqa tag on it. Then you didn't say what saw this chain was on either. The only way to figure out the top angle you like is use the chain and if you don't like the way it cuts change the angle and see if you like a different angle better. Trial and error. You'll get to where you know what you like and then you will put a file to new chain. Yes, some like myself put a file to new chain and give it a light tickle before it hits wood. Before you do this run the new chain through wood and see if you are happy with what it does new before you start changing angles. Once you're hooked on saws you'll be wanting one chain for hardwood and a different one for softwood, a backup saw, and a backup saw for that one, neither backup saw sees much action but you have to have them. Look at it like golfing do you ever see a guy play a round with just one club??? Nooooo! they have a collection of clubs to hit with. It's the same with arborists, lumberjacks and tree guys, you want to have more than one club when you hit the woods. I use two saws most often, had them modded to put more spin on the chains. Like golf, some guys have to have designer clubs so stop and have a look at the saw builders for designer work to get a Dozer, Eph, Dunn or just get em Walkerized. Then again you could open another beer and keep reading.
