Thread: Unopened C-MON HF on eBay: how old could this razor be?

Somehow, someone got a hold of a few unopened vintage razors. The C-Mon can be seen here:

My question is: how old is this razor (approximately)? I ran into this post by manah about C-Mon's and found it quite interesting. Seeing that the company moved to NY is the 1920's, and this razor box is marked "Made in Germany," does this mean that it dates prior to Carl Monkhouse's relocation to NY? Anyone's thoughts on this would be appreciated.
