Excellent, thanks!

What occurs to me is that the quality of the gearing in any case depends
on the materials used, and metallurgy has undergone almost exponential
development since the middle '80s. Remember when cars that reached 100k
miles (160k kilometers) were exceptional, and most likely well coddled
and scrupulously maintained? Not since metallurgical advances have made
possible the kinds of engineering that was hithertofore impossible; cars
regularly do several hundred thousand miles/kilometers with only cursory
maintenance. The same must be assumed to apply to telescope mounts, I
think.

I guess the question is whether or not things like PEC were routinely
compensated; I gather it is now possible to eliminate PE as a real
concern, given careful manufacture. And that could well have not been
possible before the mid-'80s.

But you're right: Older top-of-the-line products quite often not only
outperform newer stuff of lesser quality, but can be had for much less
money as well. It simply takes knowledge of the issues and a
willingness to refrain from throwing money at what is better addressed
with individual skill, knowledge and patience.

Wouldn't it be nice if the craftsmanship expected in earlier times were
wedded to modern materials at a reasonable price? Well, craftsmanship,
materials and reasonable cost are like faster/better/cheaper: choose
two of the three...

Anyway, thanks for the information!
