Machin - Overprint Selfridge London

[MikeC99]

After enjoying Alanl's Machin thread, I looked at my collection and noticed a 2D stamp with an overprint of "Selfridge London". I did a Google search and learned that Selfridge is one of the world's finest department stores. I assume that the stamp was overprinted so as to dissuade employees from using the stamps for personal use.   If my assumption is correct, was this practice employed by many firms in England?

alanl, thanks for the link to the Commercial Overprint Society of Great Britain website. I found another commercial overprint on Scott #295. The overprint reads: "Received For Thomas Moy Limited".

It occurs on other stamps of the British Commonwealth as well.
