Request: German shell cases with the letter "P" or letters "Pl P".

[Hoeksel]

For an article in the works I am looking for the following German shell case head stamps:

1) "Pl P" later than June 1885.
2) "P" before April 1888.
3) "P" later than July 1889.

This to pinpoint introdcution and stopping this way of working.

Both "PlP" and "P" are for Platzpatrone (dummy round) and used on early German shell cases. See examples.

Nothing before or after those dates, sorry....
