Help with the age of a Remington Knife

[knifenovice]

I found a mint Remington fixed blade with sheath and box. It is a RH-134 and shows that it was made in the USA. Can anybody tell me the age & value of this knife in mint condition. I have seen book values but they are for much older knives and I dont think this one is that old although I don't think it is brand new. Someone told me that some Remington is being made in China.
