The above link is nice for the Dietzgen Microglide. It doesn't have the 
CF/m DF/m scales, but is a very nice Vector type log log. Most of my 
drafting equipment from the same era was Dietzgen; it looked like the 
previous video post featured the same/

My dad has one of these; but I can't get him to part with it yet...
