There was an interseting article in Pratique about a suspect disinfection cachet from Bromberg. Denis has seen only a b/w copy of this letter. He argued that the "SANITAETS / STEMPEL" cachet differs from the sample he has in his collection: the T and the L are not directly above.
The suspect cover is in my collection now. To me the cachet looks genuine and I can't see characteristics of a bogus. In the book of Meyer there is an illustration on page 167 of a similar cachet for Königsberg. This cachet also has the T and L not directly above. My read is that different cachets of the "SANITEATS / STEMPEL" exist.
Are there further finds of this variety?
