Primus No 100, manufacturing year?

What manufacturing year can this Primus have? I cant find any year letter

 

Pre-1911, no date letter and a format of tank top legends that only lasted until 1911. Nice

 

Roughly 1898-1910 with those markings, and the parts style fits that era.
Knowledge of when certain details were altered on that stove model could pinpoint the age better.

A 1911 should have "A" between SWEDEN and Stockholm in the B.A. Hiorth-ring - and so on.

 

Hi @Oskarsweden here is the 1911 model to compare with it.

Primus No:100 - 1911
