I have some true locale, Alabama corns. They are from Walter, & the female was WC, & I have a pair of siblings from that WC female, that were sired by an unkown wild Alabama male.
From what I am told, it is the corns in north Alabama that have the metallic grey color.
Not all of them, but from what I understand, it's the ones from a particular area.
If you have an opportunity to get some from Walter, I would in a heartbeat! I have several snakes from Walter, including 3 wild line Alabama's (& two that are result of a cross with Hypo Okeetee).
Here's three wild line Alabama's (the first two are Mica, the WC female, the next two are Katzen & Silber, her offspring from the year she was caught)
