The two I have in the one pic? were found together on the same day. 1 was broken and glued.
11KBP. I’ve meet you in person a few times the first time was about 1980 in the SPR by Big Spring Nebraska. I used to take one of my grandmas cars and drive the 25 miles or a mini-bike or about anything that would start. You and another guy were looking at some collections from that area and later in the day we met and talked in the river I was 12-14 y.o.
