NWL: THANK YOU for the pictures and explanation on the early Flyer engines. Data on these cast iron guys is hard to come by and really interesting. I saw one on e-bay recently but with the normal high shipping charges it was a bit out of my reach and the ad really had no information beyond the fact that it was reported to be AF (based on what it said on the tender). I will keep looking.
Thanks again for taking the time to post the data.
Don
