Dating Former Pipes

[americaman]

Does anyone here know how to date Former pipes? I found what appears to be some older ones (that look like they are from the same era), but I am unsure of the era. He has changed his markings and font several times (even recently), so I’m assuming one can guesstimate the era based on the font/markings.

I'm committed to my marriage so this is purely hypothetical you understand, but honestly, it wouldn't work between me and a current pipe, let alone a former one. YMMV.

LOL, I was about to type dinner and a movie have been reliable for 100 years! I guess I just did.

No idea, sorry to interrupt, but every time I see "Former" pipes it does toss me for a bit of a loop processing that is the name and not some pipe you haven't picked up in awhile, etc. And they look like great pipes.
