Identification of Large cut Crystal Vase: Ajka? Hungarian?

[truststar5]

Looking for help in identifying this large red cut crystal vase?  Is it Hungarian Ajka?  Or other?  Any help in identification of maker, location, age, pattern, etc. would be greatly appreciated.

The vase is just over 10 inches tall, and 5 1/2inches across the top in diameter

Possibly Nachmann Bleikristall from Bavaria, Germany

dozens of companies made red flashed cut crystal.  I would imagine you could only find the maker by matching a known pattern.
