Congrats,
It is a model 11337, circa 2011. The 22" barrel, fit & finish, wood is usually superb.
The later "Lipseys" (21311) 20" barrel, was joked the wood was from a fir 2x4, very plain.
I looked high & low for mine (134-370xx/2012 mfg) finally found it in 2019, wanted one to go along with my BSBH 480R 5.5" Octagon.

Depending on condition you made a very good buy.
