1948-1954 "Blue Flea" Type I

I would like to show us this small stamp, also called "blue flea" because of its size. Corresponds to a postal tax rate for the British American zone of Germany, 1948-1954. I have managed to classify this specimen as a Type I, but I have seen that there are many variants of this stamp to fill entire catalogs by itself.... This one has the curiosity of not having perforations on the right side and 14 on the rest. If anyone identifies it with any of its many variants, I would greatly appreciate it.

Have you tried searching this forum? This little stamp has been mentioned several times before

murasama, check the perfs on the bottom of the stamp. It is probably closer to 12, not 14 (assuming 14 is correct). Depending on watermark it may be Michel 2BBW or 2BBZ.

Here is a chart to identify which of the 4 types the stamp is:

Thank you for all the info! To identify the type, I was guided by this website https://worldstampsproject.org/germ...l-tax-stamp/ ...let's see if tomorrow I can see the watermark.
If the stamp is not perforated on one of its sides, what is considered unperforated or roulette?I'm very newbie...
Indeed, the top perforation is 13,8, but the bottom one is 11.75.

The right side looks to be torn.
Also looks like two perforation holes at the top.

The watermark is a wave….

Watermark 3 X, the falling wavy lines. Stamp Type Za based on the shape of the "R" in NOTOPFER and thin "BERLIN" Can't tell on the "N" in NOTOPFER,, but likely the pointed "N" variety based on the previous two factors.

That would make this MiNr. 2 A Z a. CV used of €0.30.

Thank you so much! Now I will label it with correct name and surname!!
