Hello, thank you for your patience this has been interesting to find information on. There is little on the Vita-nola Company.
Here is an ad http://mtr.arcade-museum.com/MTR-1918-67-24/MTR-1918-67-24-137.pdf
from 1918. The types here in this ad are up to type 17
what is interesting is I was able to find another ad in the Antique Phonograph Society
writing to the society I was able to find this one you own was produced in 1922 and sold for 120.00 originally today these have a value of 900.00 if in pristine condition. Having shown them the photo of the one you have overall it is valued at 600.00 as the case is in great condition for the age and it does work with great sound you stated. The green paint you mentioned is the original paint for this model.
It was one that I had heard little of so it did take time to secure the information I have been able to find on this one.
Thank you for your patience and allowing me time to secure the information you wanted.
