I am new to this as well, but the year on your rifle sounds right. It's my understanding that the "model 1899" and the "model 99" are the same model. "1899" over the years simply got shortened to "99." I also have a Savage 1899 (or 99 if you prefer) in the HP22 caliber. Mine was made in 1914, and your serial number makes sense compared to mine. As far as a value, I would have to let someone more knowledgable than me help you with that. There are many things that go into the value (condition, type of stock, checkering, takedown, special order, etc, etc) that is completely over my head. Sorry I couldn't help more, but I'm sure one of these gentlemen will help.
