Dating a Peterson's Shamrock

[retrogrouch]

Hello all. I recently purchased a Peterson's Shamrock bulldog pipe, shape 998. I believe it is fairly early but I am not sure when it was produced. I am hoping any Peterson experts out there can help. Take a look at the photos and let me know what you think. Thank you.

Thank you but I think those are silver hallmarks. I'm afraid the Peterson markings on this band are only decorative.

Oops you're right. Didn't realize that, sorry. Good luck!

"Later they stamped their pipes with "Made in Ireland" in a circle format (1945?-1947?) and still later with "Made in Ireland" in a block format (1947?-1949). The "Made in Ireland" block format came in either one line or two lines."

I saw that but I also saw this, " "Made in Ireland" block format can be another headache in dating Peterson pipes since this stamp was used in the late Patent Era as well as the late 1940s. So for a guide we must take into consideration the style of lettering Peterson used on their pipes. From the start of the Patent Era until somewhere in the early 1930s, Peterson used the "Old Style" lettering that used a forked tail "P" in Peterson," I believe this is the old style P. This is why I am somewhat confused.
