Chinese Melon shape jar worn mark help

Picked this up on my trip but can't figure out the mark to tell if it is even old.
It is 9" tall

There's not enough of the mark left for me to make out what it was, but poorly printed red marks like this are pretty much exclusively post war, generally 1960's onwards. Could be mainland, Hong Kong or Macau, very hard to say.

 

Thanks, I didn't think you could make it out. nbd.
