Here is the stamp, R5a:

In his pamphlet on printed cancellations, Howard Beaumont lists one for V. & S. as follows:
"V. & S. / FEB-20-63" printed vertically reading up in Roman caps 3˝ mm high. First line 15 mm long; second line 21 mm.
On this one, the top line is exactly the same. However, the cancel obviously reads down instead of up, there is a period rather than a dash after "DEC," and the second line is only 2˝ mm. high and 19 mm. long. So it's definitely different. On the other hand, Beaumont says that in some instances he had only one example of a cancellation to work from.
Any thoughts? I don't know if the cancel is so scarce that someone would be tempted to fake it on a very common stamp.
