Faber-Castel a maker of second tier fountain pens, needed a first tier pen so bought up Osmia, and then having an ego problem immediately started erasing Osmia's cap jewel, clip, name onthe pen and name on the great nib...Bought up in @ 1950 erased before the end of 50 and Faber Castel died as a fountain pen by mid '60's if that long.
In I believe the German bosses chopped off the head of workers bold enough to show their pen was as good or better than the boss, Osmia had three-four finial jewels, and at least 4 clips, one pure genetic.
That is the only reason I can come up with that.
In the following pictures, I have them, and or occasionally I found a better picture than I can take of a pen I do have.
1938 The Boehler Brothers split up their Osmia factory....and Boehler continued using the same model numbers as Osmia.
So on the whole when talking 30's Boehlers I consider them Osmia pens.
A mid '30s push button filler 222.
Click to get a better view...a mdl 76 I have a couple BCHR in 72 and 76 which is a medium-large pen, but the borrowed picture is better than I can take.
As I said, I don't know why the generic cap.
This pen I do not have...some 15 years ago, when I was struggling with thin air of €50 for a used pen, this went for €350. Osmia Supra Deluxe, and a hell of a 4 B signature nib.
This is the pen they chased and caught Soennecken and MB with.
Push button.....Soennecken, MB and Osmia and any of the rest did everything in the world than pay Pelikan to use it's piston.
This I have. An Osmia on one side Faber Castel on the other side...the next year on the same side and then erased...the pen that started my crazy addiction. A 540.
It was a steel maxi-semi-flex, when I didn't even know what semi-flex was....all the noobies were enthused by wide thick lines of ink...and this did that...having ease of tine spread...then died needing a new cork gasket....and It was until later I found out about semi-flex and maxi-semi-flex nib.
I was off to sell at my first flea market and we had a drawer full of old inherited fountain pens....I said, 1€ for the regular run of the mill old obliterate leaking things including the gray Esterbrook DJ and €5 for this one....Wife shook her finger and tasked me with looking it it. at 20:00 I started looking.
My in my wife's jewlery box jail, P-75 was then worth 3225...and this €5 Osmia was worth $250...So 02:00 I had a collection.
This is someone else's picture I use to show the Osmia brand mark finial top and the small diamond with the nib size inside the semi-flex nib. This is a medium-small (very popular size in Germany) a 62...which I have in black and gold. Bohler
One day the big one just fell apart with crystalized rubber.
'38 Boehler 54 Gold...full tortoise....when I buy a pen, I get the picture for my use.
I do have some simple non chased black and gold Osmia pens also.
