sigh... sorry. Too early to filter myself... ok, awake now... hehe
here is a pic I call the "Wall of Howe"
[ATTACH=CONFIG]398165[/ATTACH]
from left to right ( Model A parts machine, Model B, Model A Repainted, Model A awaiting it's table)
Note on the rightmost Model A there is NO above bed stitch length adjustment!
I looked all over it and found that it is located under the bed right next to the feed dog cams. It seems that they evolved "to" the design that broke on the other two...
the rest of the pics are in the album:
