Logs but not Lincoln?
 

My family hung onto these since I was a kid in the 70’s and I’m now passing them on to my son. The logs are stained orange with light green shingles that sit on long green poles, overlapped just like a real roof. Everything is wood... no plastic roof trusses like Lincoln Logs have. There are small green pegs to act as dowels between the logs and make the structures more solid. The scale is roughly double that of Lincoln Logs. Amazingly, none of the set appears to be missing. Any idea what these are?
