German (Notgeld), how to find ID-numbers

Hi experts

I have coins from German notgeld. A lot of these coins are not to find in the numista database. I can add these coins to the database but I have no ID-number of these coins. Where can I find a Funck- or Menzel-number?

Such as, 5 pf from Beckum, mat. zinc, round 19.2 mm, thick 1.0 mm, 1.62 gr, ma



Such as, 10 pf from Beilngries, mat. zinc, round 20.75 mm, thick 0.9 mm, 1.91 gr, ma



Thanks for help

I do not think these reference numbers can be found anywhere on the internet.
Like derf, I managed to buy a 2012 Funck version, but it took me a while to find it.Geoff
It was worth the wait.
Still looking for the Grabowski banknote catalogue.

​If you google Notgeld, you often get a hit from the MA Shops. They often have the Funck ID.
