Help needed Hagen Rotary model brb
 

I am looking for any help to identfy a machine that was given to me. I have patent numbers of 1.711.792 and 2.001.966 the serial number is N146390 and stamped made in the usa by National. The machine is a double to a Coranado by Gambles.
Thank you for any help given.

Welcome! Can you post a picture of the machine? It will go a long way in helping you figure out what you have. Meanwhile this might help with a ballpark date. As a rough guide, patents were good for about 7 years. I think there are exceptions to that but it's a start. Here's a list of patent #'s and what years they were issued:

You know the machine was made after the last patent date so if you figure from then until 7 years later you're probably pretty close to right. Some manufacturers left patents on after they expired so it's not an exact thing.

To add to what Rodney told you, National built the Coronado machines for Gambles until 1954. Don't know how many different models there were though or if that will help you at all.

Thank you! I have my friend and caregiver coming out today to take photos of the three machines I have.
Two I use daily the White and Majestic. I admit it took me till now to figure out how to get back to the post to
thank you all;) As the Hagen has forward/reverse 1234 I am exited to see if I may reserectic it. As to Cari in oly I am in
Shelton.

Another "local" then! Considering the worldwide nature of the board anyone in the same state is local to me.

I was sent the patent data, according to it is 1927 but the person who
gave me the machine thought it was a 50's vintage

The fact that it has reverse makes me question the 1927 date but then again I know next to nothing about any pre-1950s machines. Being in Shelton, you know you have a wonderful repair person right there.

Molly has been very helpful to me on more than one occasion.

Patent dates don't mean a lot - W&G had the most recent patent date around 1895- however that was still on machines made in the 1940's as there was no reason to make changes to something that worked then and still worked 45 years later.

The only thing you know for sure about patent date - it was NOT made before that.

Likely it was made in Japan.
