I don't know these cards, but Walter Sigg from 3Dentertainment (he sells on ebay and from his site) is very well versed in all things stereoscopic, lenticular, vari-vue,viewmaster... Maybe he can help you or can point you in the right direction...
Here's his contact page on his site:

Hope this helps!(tell him "lawnninja"/bek sent you! I buy lots of lenticulars from him and will be hopefully purchasing a lens to shoot my own stereoscope pics soon!) He is a wonderful resource!
Best wishes,
Bek
