I am a stickler for calling things what they are. If a truck goes by and it is filled with Coke bottles, it is not a Coke truck, it was not made by Coke, they made soda, not trucks. The same as for this unit, it is not a Texaco, it is a OPACO, they made it under special order from Texaco (meaning Texaco paid extra to have the lid embossed with the Texaco logo).
So now, if you happen to be looking for parts (which it looks likes you are not beause this unit looks very complete) you should be asking for parts for a OPACO.
A couple of OPACO unit are shown in my Gas Pump Identification book, but none as generic are yours. I am sure I have info on your unit, but do not have time to look them up.
