Model 10 break action pistol info , please help

[Bolonytony24]

Hello ,
just joined as I have been trying to find information on a model 10 break action .22 long rifle pistol I have . My Google foo is not strong but I have found this pistol seems to be a model 10. I have attempted to fire it but seems the firing in may be worn or too short. I was going to order one but I have not been able to find much of any information on line. It has patent date or April 27, 1920 , 22 long rifle but I can not find a serial number on it. I have not removed the grips so I am curious if it’s under there and if any parts are available.
Factory I assume is hard to find so new production is fine if available. Also this gun seems to be immaculate if it’s from the dates I am seeing they were made.
What dates were these made from and have any been made in more recent years?
Thank you I’m advance for any information .
