Okay, y'all! We finally think we found Shalom's name! The tattoo turned out to be 2333Y which matched with a sorrel gelding with a blaze and two black spots on his nose (which matches him!) and no other markings. He was in Ohio for a long time which matches what the rescue said. His name is apparently Dot Dot Zoom. We've found his Equibase Profile and a few videos, possibly one photo but I really want to find some more photos if anyone can help. :P He was foaled March 18th, 2005.
