Nope... All the lighting products on my '08 210WBS and a friend's '08 FunFinder were Command Electronics. That amber cover fit my outside light perfectly and the LED upgrades I did on the tail lights were perfect plug and play inserts for their tail light assemblies on both our trailers. I don't know why they are saying they didn't make those assemblies as, if I remember correctly, when I took the tail light assemblies off to renew the caulking while I did the LED upgrade on both the trailers, they were even stamped with the corporate name and part numbers.
I would order the lens (if your porch light looks like the one on their site) regardless of whether they admit to manufacturing the lights for your 139 and I would find it really strange that CruiserRV would use a different company for the 139 and Command Electronics for the 210WBS and the 244 that my friend had (he totaled it this past November...). I even ordered some replacement lenses for some of the inside lights when I was experimenting with LED mods for those lights (I wanted a frosted diffuser) and they, too, were Command Electronics and their lenses were a perfect fit to those interior lights...
In the really bizarre unlikelihood that you do have a "one off" from some other company, you could order the Command light assembly and just replace the entire assembly. They are a two screw mount and easily swapped out...then you'd know for sure it was Command Electronics!
