Thank you, Gary.

When I sold my house three years ago, I donated what I could of my nav
library and (sigh) had to just pitch a lot of it - including my
collection of every NA from 1965. I have in my mind that a picture of
the device was in one of my Bowditch's - as I recall it was an edition
with a dark blue cover, whereas I think the 1977 was medium  green?
The description in the pages you sent sure fits, though.

Thanks again,  Hewitt
