I don't own Windham rifles but a friend of mine has been singing their praise for quite some time. I personally find them to be on the expensive compared to their piers, but they indeed sell chrome lined barrels extensively on their rifles. Pot meet kettle.
I never said they don't; I said it wasn't mentioned, which it isn't when you Google "Windham Weaponry barrel steel". You get (or at least I do)
Barrel Material: 4150 Chrome Moly Vanadium 11595E Steel w. M4 Feed ramps
ETA:
Windham lists their barrel specs in three separate and disjointed categories. Why they choose to list M4 feed ramps with material, but mention profile and lining separately, and twist rate in yet another category makes no sense, but that's how they've done it. So, yes, they do state CL in their 4150 barrels. Just not in the same category, which is rather nonsensical, and why I missed it. If I were going to break it down that much, I'd detail the barrel extension (different material from barrel) and feed ramp profile on it's own.
Basically everyone else chooses to state material completely on it's own, or include it with other specs that also detail lining. None of them detail feed ramps with barrel material as the only two in a spec grouping.
