Dallas imported a lot of WOF Hotchkiss Jeeps as well as dealing in "projects"; I have known Steve Rivers for at least 35 years and he has worked hard to get where he is now.
You are quite right about the Butler Sidelights. When I was building the replicas for the Speilberg Empire of the Sun we bought a lot of NOS ones still in their Army packing cartons, and I have seen a few at Automeets.
As the Guide Marker lights are not legal in both position and even if you take the Flag Masks out, and in many cases they had gone altogether, it made sense to use the Butlers as they were of that period.
As Jeeps escalated in value, more came to light and were being restored. It was rare for these to be so particular as many of the restorations nowadays are quite fanatical about what was fitted when etc. The knowledge simply wasn't there, or if it was many people chose to ignore it.
In 1983 Hotchkiss Jeeps did not have the same values as their WW2 cousins - but this has now changed and the WOF vehicles usually command the same prices, if not more. They are nicer to drive and with 24volt systems start every time and are much more attractive propositions for people who just want a "Jeep"
I'm afraid I am a WW2 person, in spite of having an MD Juan body on my truck, and several other modifications, at heart it is still a '44 GPW
When I had the 1940 K2 Austin Ambulance that had a 12v system from original, but the Butler Lights were atrocious for nightime driving.
I bought a pair of new Butler Tractor lights and put 12v Sealed Beam units in out of the Triumph Stag. At least I could see where I was going! The sidelights were adapted to take twin-filament bulbs and served as indicator lights as well. When I sold it I gave the new owner the original 5" Butler lights as part of the spares I had with it. They were interesting as they had 1/2 covered blackout lens with hoods and lift - up doors to let more light out
