takin pics of single marbles is really hard...hard to positively id those but your description of the first ill conclude thats it a vitro...either a conquerer or a brushed patch....the bottom one can be one of several brands..alley- ravenswood- champion.....maybe another pic of both of them together--farther back straight down on them would be easier to id...
Hey Duffy that first one looks like it could be possibly peltier and like you said it is easier to tell from a little further back where you can see more of the marble. I also agree with your second marble assessment. ksmith
