As you can see the inside is in great shape. Milk Glass interior, the seal is intact and in good shape. My question was what to do, remove the glass?

I have one that looks just like that... inside and out.

Does it have the Long, metal holed, solid element humidifying device along the bottom, front that is held in place by those 2 metal swing brackets???

Low

Remove the glass. That Spanish cedar is likely old and musty too. Line the bottom, top and sides with new spanish cedar and you have one great looking humidor.

Lowman, I dont have the metal humidifier.... but i gues it was held in place by the two metal clips.
