Smith Corona Vintage Typewriter Margin Rack Alignment Stop Adjustment by [[Phoenix Typewriter]]

If the "Hanks Effect" was really so prominent, then we should see the commensurate rise in price of 5 Series Smith Coronas and particularly the Clipper and the Silent which he's also mentioned several times. In fact, he's said these would be the typewriter he'd keep if he had to get rid of all others. Given this fact, it has to be, in part, a variety of other factors which inflates the prices.

Personally I think that it's a combination of the fact that they were manufactured at the peak of typewriter use and manufacturing and before companies began using more plastic and cheaper manufacturing methods, but were also done in a later timeperiod when exterior design and color were on the rise as a differentiator in the marketplace. Quality, form, and function become part of a trifecta which drive desire and collectability.

Duane starts out by showing the two adjustment screws for the upper and lower case motion adjustment on a 5 Series Smith-Corona portable. (This should be the same across several decades of machines and include the 4 and 6 series as well.)

Smith-Corona 5 series drawband and mainstring attachment and tightening.

Smith-Corona Series 5 and 6 typewriters had a small piece of rubber around a portion of the escapement which can wear out or become damaged. This in turn causes the escapement to not work properly and cause the dogs to get jammed resulting in large movements of the carriage while typing or spacing.

Joe Van Cleave calls it the "return silencer" and replaced his by tracing out the damaged piece on a sheet of 1/32" rubber and cutting it out as a replacement.

Duane at Phoenix typewriter describes replacing it with rubber tubing (possibly something like heat shrink?) instead. See: https://hypothes.is/a/tG4BWk77Ee-jczsjoM8SzA
