Looking for Kensington wood moulding supplier

I don't know what the first link is, but the 3 frames in the bottom link are Larson Juhl mouldings and Kensington is the name of the collection those come from.
It probably is LJ, but that's a pretty liberally replicated profile. There are a number of vendors that have extremely similar mouldings. LJ does call theirs Kensington though.
