You do not see these shapes anymore...kinda old school... Sweet!Just realized that 2022 is the 100-yr anniversary of the beginning of the 'Irish Free State' period (1922-37).
Here are a couple of mine, along with a period box. Top - 606 Natural. Bottom - 588 Kapet.
I have three others that I'll try to organize into a serviceable photo.

Sure enough, I already got another Peterson - and I love it / them. This one came as a "freebie" with a couple of other pipes in a package deal with an accessory I wanted. I figured the pipe would make the purchase worth the $ and in fact - the $ would have been worth the pipe alone.
