Age of a Hyfire 1 Based on Serial #?

Hello to everyone, I am new to the forum and considering a stoker stove. Is it possible to find the age of a LL Hyfire 1 based on serial #? Also with stoker stoves and this model in particular what is the average life expectancy on average? Trying to decide whether buying used is worth it or to just spend the extra $$ on a new unit. Thank you all for any help.
