I found a limited number of these OWL chips with the number 3071 on the back the mold is triangle. I have no idea whare they are from.If any one has any info on these please let me know. I'm going to sell a set of one each (yellow and green chip) for $7.00 and $1.00 postage till the sets are gone. If interested in a set let me know. Also will be posting some more old mold chips I found. Thanks Top" Top@TopUsmc.com
