[Boatanchors] Gonset G76

[Peter Markavage]

I looked at the GIF files and the DJVU file and saw no difference in the
readability and  line and print registration on the schematics. Wherever
the original "schematic" that was scanned came from, it was most likely
not a Gonset original since you can clearly see where individual sheet
copies were butted adjacent to each other and secured. The "line"
registration (line to line) between the sheets were way off. I have no
original Gonset schematics, including the G-76, that look that way.

Actually, I've found the printed quality of many original Collins manuals
of that era to have little difference between the quality of other
manufacturers of that era. Gonset, Hammarlund, Hallicrafters, Heathkit
and a number of others all produced excellent original manuals. The
faults often lie when one attempts to scan an original with a poorly
designed scanner, and/or in a lower resolution to keep file size down, or
a scan of poorly made replication copied and printed on a low resolution
copier and then the finished product scanned with a low resolution
scanner.  Contrary to popular beliefs, there is an art and/or skill
evolved to producing an accurate and 100% readable replication of a 40 to
60 year, or older, manual. The old adage works here, "you get what you
pay for".
