Good call Tommy--I agree---
The lower right may be a Vitro--the other two--well they are all patches---
Top right--Vacor--bottom right----Vitro.
More opinions are needed here---
Marble--On!!
X2--not from the USA inho.
To sell a contemp in the good ole USA--the mark must be higher than these.
Are there any new makers that you can ID over on your side of the Atlantic?
Marble--On!!
The "Special Order" Atmospheres came in @ 45mm and 50 MM.
I have one of each- neither has any reaction in the clear base glass. The small ones show no such reaction either.
Some of the yellow colors in these reacts as orange.
Check closely for pontils or cutoffs on your two Mojo--they may be contemps--or not.
Old handmades do react like your two do--sometimes. Compare to any "Sulphides that you may have.
Marble--On!!
Nice image!
I think that "Hurricane" is ruled out. It may be a Jabo but it may be a WVS as well.
More opinions are needed--maybe a few more nice natural light images too.
Marble--On!!
Patches are tuff to ID sometimes. I do not see any Masters.
The top one may be an Akro--that what I would sort it as. The middle one--Vitro--the last one--MK or Vitro.
Just my humble opinion.
Marble--On!!
I had lived in the woods for seven years before I met my wife.
We lived in the woods for two years before we were married.
We are now quite "normal", living in a house with a back yard(with dogs).
Marble--On!!
