Need Some Help With Peterson's Patent Hallmark: [K] [IV] [ P]

[woodman]

I will be thankful if any knowledgable peterson collector can shed any information on this unique hallmark, [K] [IV] [ P], that is marked on the nickel metal band of a Peterson's Patent #4. This is not the normal K&P hallmark. Thank

I've never seen that before. I'm interested to see what this is.

I too have never seen that before,but you state it is a nickel band.Nickel is not hallmarked.
I am assuming that it is like the usual K&P stamped on the band but why IV instead of &
watching with interest

Anyone know how to contact Mark Irwin from Peterson Pipe Notes

I can only guess that it can be one of the three:

• A secondary & experimental way used by Peterson to mark the 4th grade of the pipe: one mark with the number "4" on the shank and one with Roman numerals IV on the metal band.
• It may be that the 'IV' mark stands for 'Irish Volunteers' that was a military organisation established in 1913 by Irish nationalists in Dublin. Pipes were often used to express political or social allegiance, being decorated with a word or symbol. This pipe could have been specially commissioned by members of the 'Irish Volunteers' asking that instead of the common K&P hallmark, the K-IV-P will be marked. This option is accurate chronological to the Patent Period. ​
• It may also be that the IV mark represents an old an obsolete legal abbreviation symbol for a partnership or cooperation between Kapp and Peterson.
• Again, I do not know the answer so any ideas will help.
