Upside Down Made in Germany Stamp

[bwavefront]

I recently purchased a 1920 Commercial and the Made in Germany stamp is upside down. I did some research on the forums and I understand the stamp could be placed anywhere but I didn’t see any info on the stamp being upside.

My main question is has anyone seen this before and would this make my Plain Jane Commercial any more or less unique.

I’m guessing whoever did the stamping had a bad day or too much to drink but if anyone else has a better explanation let me know.

Thanks in Advance
