I've been through several possibilities on the Browning 'Date Your Gun' website at
Browning Date Your Gun
The most promising is here:
22 Semi Auto Rifle
The codes here are consistent with the one you put up, and describes itself as the '22 Semi-Auto Rifle'
From this document, single digit before the T indicates manufacture between 1956 and 1967. The T means 'Long Rifle Caliber'. The remaining digits are the serial number. Since they started with a four digit number, and yours is close to 100,000, I'd guess closer to the end of that era than the beginning. Later than that and the serial would start with two digits for year of manufacture. Earlier than that, there are no serial number records. Manuals can be found here :
Hoping this answers your question!
