Help ID oiler M1 Carbine / 1903 Krag ?

Please help ID the two oiler's below. Not sure if they are for M1 Carbine, 1903 or Krag.

They look like M1 Carbine to me... Krag oilers, all I saw, were bright and had a bigger cap. This cap is close to the outside of the tube. Krag is far bigger, you can't mistake them once you see them...look them up on line.

Carbine. Krag and '03 Springfield oilers were nickel plated brass. The Krag's was 3.25" long too.

And then there's this. Dunno if the guy knows what he's about though. Especially as none of the original makers made all the parts.
Oiler Markings. - M1 FAMILY

thanks for the help guys!

They look like after market M1 carbine oilers. Some early M1 carbine oilers were marked on the bottom to different makers. Later carbine oilers were marked IS all in a circle. BK, SN with a number. There is an SW on the cap that has been up for debate. And a Poly Brothers.
