All About Pocket Knives

i'm a rookie when it comes to roosters and i'm trying to research the early ones ...i originally thought that I was just looking for "frank buster cutlery" without the "celebrated" ... always having two roosters fighting on the tang...but I've found that there are possibly some earlier examples out there with simply "Solingen Germany" on the front tang and the usual "frank buster cutlery co." on the reverse ... no image of two roosters fighting on the tang. Curious to how early or common these are...and also, is it possible for a secondary blade on a rooster to have no markings at all and still be an original blade??? for some reason I was thinking that all blades were marked.
Any information, examples or feedback would be greatly appreciated...thanks!

Hello and welcome.
First of Mr Busters FR knives came over in 1976 or 77.He did have some special order knives before that but I cant think of how they were marked.
As for your question about the tang mark,I just checked all of mine and all blades are marked, but I am still not 100% on that.

thanks knifetime for the info...and Happy Holidays!!
