I thought that the dude from Mountain Molds had retired but there is a modernish website:

https://mountainmolds.com/

I couldn't find any history listed but the Facebook site starts around November 2023.

Anyone know the history and if this version is legit? Anyone bought a mold from them recently?

I bought a Mountain Mold back in 2013-ish - I want to buy another but not sure if this is the same crowd or what.
