Could very well be Jabo's, hard to say from a couple pics.
Peltier made some shooters in this size and color combo, and sometimes (at the larger sizes) the pattern can get a bit unpredictable...But a lot of Jabo marbles can be confused with vintage so take it with a grain of salt.
For your question, if Peltier? Probably, somewhere between 50-80(?) years old, but see if anyone else chimes in. Some of the Jabo guru's might recognize them
