Bob, Thanks for finding another one, I always knew that these where NOT USGI Oilers. I just been trying to find out where they came from. Someone had to make them and very, very few at that. I was more curious to where they originated from and who had used that US marking. The one in your picture has the same 2 dimples and that 1 dot in between the 2 letters. It looks identical to the other 2 oilers. One day hopefully someone will know who tried to make these. Maybe some Mfg Co. started to use that stamping and very, very quickly changed it. Who knows ? Thanks for sharing that Bob.
