France Scott 304 with unusual cancel

[b***@gmail.com]

Can anyone help me give some information on the cancel shown at:

A correspondent has asked me about the significance of the cancel and I don't recognize it, nor do I find anything about it on Guy Maggay's site nor in my literature. (My interest in French cancels dwindles after 1900, so my reference works become less useful for such questions.)

Thanks in advance for any help.

Hello Stan,

With the help of the French speaking news group
news:fr.rec.philatelie
here is the explanation.

This is a Belgian cancel (named Diamond cancel) used here on
a French stamp as - by mistake - the stamp had not been canceled.

See some examples here :
