Being an extractor makes it late production, the old 1:38" would have been an ejector. New production SB2 frames have a CBA serial number prefix, made in Ilion NY, the only way to determine actual year of mfr would be to call H&R(Remington) in Madison 877-776-9292 and give them the serial number, CBA just denotes May 2008-on production, no specific year. Bought new last year makes it NOS, H&R closed the Ilion plant in April 2015, I suspect there was very little, if any production in 2015 after the lay-offs in 2014, 2014 was the last year of H&R catalogs publication, there was no 2015.
