No. 45 Push knob Hard Rubber
This pen is from the personal collection of Joudenali. Watch out for reviews of truly rare pens from his treasure chest!
This No. 45 has a push knob filler and is made of hard rubber. In 1924 Montblanc introduced the "Meisterstück" series which was intended to be the company's top-of-the-line offering. At that time, the pens were numbered based on their price. So, the No. 30 meant that it cost 30 Reichsmark (RM) which was the currency in Germany at the time. The smaller numbers meant that the pens cost less but also that they were smaller in size. The smallest pen in the line up was the No. 20.
The largest pen was the No. 45. We have examples of an earlier black safety filler (link) and a super rare mottled red safety (link). Interestingly, this hard rubber version is longer that the others at 13.8cm capped.
There is a beautiful and large size 8 nib attached to this pen, with a "45" inscription on it. These were produced in the late 1920s. As we already know, the push knob filler technology was only introduced in 1929, so this pen must have been a later variant of the Meisterstück series. Also, celluloid versions were introduced in the early 1930s. Considering these facts, we can say that this particular 45 in review was probably made between 1929-31.
Now, this 45 is no ordinary 45. It has a rather rare and special clip. The "ball clip" design is period correct, and this particular clip is seen on one pen in Collectible Stars I. But it is no ordinary ball clip - this is a one of its kind! Apparently, different variations of clips were available for the Meisterstück series.
