Thanks jack. I figured info would be scarce unless it came from you. It is porcelien i chipped on the back edge where the back plate goes.When i bought it the back cover was missing. I asked and recieved one fron a member of this site. can not think of his name but one nice man and great to deal with. As I feel most members of this site are! I also have a Mod 25. I don't know how rare they are but don't see very often for sale. Anyway Thanks for the reply. Allan.
