I’m submitting the attached photos on behalf of an IAA member.
The headstamp reads “BREV. O. CERPELLI CAL 16” (12, 20 on the other 2), and I assume this is a reference to a patent by Signor Cerpelli though I am not familiar with it.
On the top rim (mouth) of the shotshell on all 3 is written CARTUCCIA LUBRIFICANTE.
I could guess that it is either one of those odd shotshells intended to be fired at the end of a day’s sport by lazy shooters who don’t want the hassle of cleaning and oiling their shotgun OR it contains a load of premium olive oil which, when fired, brings down the bird, removing all feathers and preparing said bird for the rotisserie, all in one shot, so to speak ?
A sensible response would be appreciated !!!
