You will get no more than what you are currently getting !! We are simply volunteers and there is no one on the Kovels site that will help you any more than we can !! They do not have staff that hhelpps and if they did it would not be correct !! The price guides are out of date and they give the wrong impression to those that do not follow the current selling trends !! This is a public forum and subscription is not required !!
The link above will give you some company info !!

You should hold in mind that subscriptions are what keeps this website alive. I mean, you were obviously incapable of using “TST Vitreous” in a search engine like Google so far, hence I would assume that you really require all assistance you can get.

In your case however the true producer of these items is irrelevant. Not only are they pretty damaged (cracked), they were also clearly (re)decorated by some hobbyist, which nullifies all former producer/age-related value.
