The Baker Brush model was one of their Batavia lines. As such it lacked the draw bolt & firing pin blocks of the higher grade Baker lines. I have had a couple of the Batavia guns over the years, a 12 gauge Batavia Special & a 16 ga Black Beauty, both with steel barrels. Even though on the low end of the Totem Pole as far as Bakers go, they're not bad guns. Certainly well above the myriad of JABC's which infiltrated the country in the same era.
