ID help KA-BAR, UNION CUT

[LKSKNIVES]

I am attaching pictures of a KABAR and a Union Cut. The KABAR I think would be considered Bird &Trout. I think the handle is celluloid either gassing or considered cracked ice?
Not sure about the Union other than it says on the blade and the handle is wood. If anyone could give me an age that would be appreciated.

Thank you very much
Steve

Absolutely beautiful knives!! The top one is a model 206, I don't know the model of the fish knife. The 206 is late 1930s, the fish knife is late teens-1923. I have examples of both but would like yours if you ever want to sell.

Love the knives! I don't know if the first knife has a celluloid handle or not, but it is definitely cracked ice. I do not see any evidence of outgassing from the photos.

Thank you both very much for the information.
They are out of my father’s collection. He has been gone for a very long time. I’m trying to learn as I go. I am the only one of us who did any collecting Lionel trains and I am selling dad’s stuff and thinning my stuff also. Those knives came out of a R-H-22 Remington knife roll. I have more some have some rust.
