The 2N-10181-B is the kit part number, released in 1945, thus the '2N' part prefix code. 2N Model production did not begin until October, 1942, but those were the wartime models -no generator. Standard 2N production with rubber and electrics began in early 1943. The 2N-10000 generator came with the tensioner mounted on the barrel. Normal 2N production began ramping back up slowly, remember, there were wartime restrictions on all US manufacturing then so part suppliers to Ford had to also ramp back up slowly as well. Somewhere along the way after 1943 it became evident that the 9N-10000-C generators still in use would benefit with the new tensioner so they designed and released the kit as an optional dealer accessory. On a new 2N tractor, the belt tensioner was standard equipment on the new generator.
