Help identifying capacitors

[Mayday]

I've had a bunch of these, NOS, in my parts drawer for years. I don't remember what brand, type etc they are.
Anyone that knows?

They are "domino" mica capacitors, and they were made by a French manufacturer, P.I., probably disappeared or merged by now

Thanks!
I knew I bought them for some reason all those years ago.
Not familiar with the term "domino" Mica though.
Silver Mica I am familiar with.

They are silver mica: the domino appellation refers to the transfer-moulded thermoset case, which is reminiscent of the domino shape (sometimes with the dots, when they are color-coded)

Thank you very much 🙂
