star wars - Interrogation droid syringe "British Made"

In Episode IV: A New Hope, an interrogation droid is used to torture Leia.

This syringe is clearly labeled "BRITISH MADE".

Obviously, Britain isn't in the Galaxy Far, Far Away, so this poses a problem for sticklers for continuity like... um... almost everyone on this site. Knowing the penchant Lucas and other Star Wars writers have for questionable retcons, I have to ask:

Was the appearance of "BRITISH MADE" in a Star Wars movie ever retconned or mentioned elsewhere, at any level of canonicity?

Note: I realize the label is all but impossible to see in the film, but I have heard people claim that they saw it there. Difficult for sure, but perhaps it is possible.
