Need help ID-ing some Glass Blowing Tools

[MrsHackula]

I know it's a strange subject, but a friend of ours has some glassblowing tools he wants to sell, and we're trying to find out more about them for him.

Most of them are marked with a Murano hallmark and the date 1923, and the most interesting thing is that most of them are also marked with a hand-scratched Star of David.

Hubby thinks perhaps these tools were scratched with the Star of David in order to mark them for Jewish use only, during WWII. We don't know that for sure, but it seems plausible.
