Yes, they did. And a fair number of them I would think, but we don't see a lot of them turning up. For one thing they can be hard to ID and and I bet a lot of them did not survive having been relegated to door propping or paint stirring duty by unknowing persons.
Of course, those would be old cues. I am unaware of any of their "modern" cues being unmarked.
Seventh cue in this picture is my unmarked Viking:
I don't know of any online resources for old Viking catalogs. Bluebook has some stuff on them.
how old? The one i just got has a smoke stain, black leather wrap, and white pearl rings at the joint (stainless steel). I'll try to get some pictures up soon.
Well, I think after around 1980 or so they were all marked. I am not an expert though.
I am still trying to pin down the age of my own Viking. I have two other Vikings but they are a 1980/81 and about 1995, both marked and easy to ID from catalogs.
Here are the pictures i took. Notice that the butt cap is threaded. The original owner told me he won it in a tournament and that it is a viking. But it has no markings of its make.
