Interesting that it is listed to operate a Thorn/GE 2D lamp, why not try it? Find the date code stamp on the bottom yet?

May all the great lighting technologies have their place in history.

1086 on the bottom of that ballast is that Oct 1986?

No LED gadgets, spins too slowly.  Gotta  love preheat and MV. let the lights keep my meter spinning.

That is interesting. Most of the ones I have seen that will run 30 watt tubes specifically mention 30 watt T8 only. Yea, you now need to find a Thorn 2D lamp and socket.

Preheat Fluorescents forever!
I love diesel engines, rural/farm life and vintage lighting!

Yet the model number is L-140F-TP, the same as a modern Advance preheat ballast that is still being sold. I wonder if the new ones will run 2D lamps also. Of course, these 1-lamp F40 preheat NPF ballasts will run many types of lamps without overheating (F32T8 included). I have the Universal version.

I like my lamps thick, my ballasts heavy, and my fixtures tough.

I have some of the more modern ones I got NOS on eBay. With a Sylvania F30T8 lamp and a Leviton FS4 starter, the setup is disappointingly not blink happy. A mere single starter opening strikes the lamp but otherwise it operates satisfactorily. I measured the OCV at about 200 volts which is not quite enough for the European F36T8 lamps. I haven't tried it, though as I do not have such a lamp yet, but someday...
