My Stan Baker BB has chokes that are 2 1/4 inches long, winchokes which is what Baker used are supposed to be interchangeable, but they are only about 2" long ????
Have a standard bore 12 Ga. Remington 1100 barrel that Stan installed Win-Choke type tubes in years ago. They measure 1 3/4" overall. The muzzle is swaged as were most of Stan' early choke tube installations. FWIW
Mine is an 1100 barrel as well it is also swagged with a higher than standard rib, The chokes look like they should be winchokes as they have the knurled end with dimples to accept the winchoke wrench but the seem to be longer than other winchokes I have seen. Hope someone has similar chokes so I can find out who made them. Cheers
