dial mounting.
« on: July 29, 2010, 07:19:02 PM »
Why do some 500 sets have 3 screw mounting? most of mine have two screw mounting. i have 2 with 3 screw mounting and they seem sturdier. Did they stop using 3 screw mounting to save materials?

The three-screw mounts were used on the early 500s.  They switched to two-screw mounts sometime in the late 1950s, most likely to save cost.  Someone here will soon supply more details.

AECo did the same with their 80 desk phones. Then when the 80E came out in 1975 they reduced it again to 1 screw!

I'm sure these changes were all done to save material cost as well as time to manufacture AND maintain them.
