I have a martin and shwartz 70 but it has a fancier art deco style top and place for ad glass on top, unlike the one in the gas pump book. The frame for ad glass cannot be taken out as the bolt is grinded on other end. It does have clips to put glass in, not sure if this will hold it in good still.Will this take standard size ad glass, it seems a little smaller than the normal space for ad glass.
