Your engine looks really familiar to me, and the one that I have came out of a Husvarna. . I don't know if there is any thing left in my junk box that could give any additional information except it appears to be a really well built engine for the most part. Mine has a scoured cylinder, and I haven't really worked to diligently on it. I am in the process of getting a Model T ready for the reinactment of the 1909 cros country race that went through here. I don't plan on going with the race, but will be part of the celebration when they get here. I will see if I can gather info on the Husqvarna and pass it on. Flathead
