model 62a with short barrel|Winchester .22 Rim Fire|Forum|Winchester Collector

hi, just read the post regards model 62a with 20in barrel,  well i have a model 62a  with a 16in barrel,  i have several  62s and 62a,s in my collction to compare it with, the muzzel is a perfect match for the standard rifles, there is no loading port in mag tube as the tube mounting ring is in the only place left with enough room so you have to take the inner tube follower right out for loading, the bluing matches perfectly the rest of the rifle,  on top of that i also have a model 62a  with a 20in barrell, again everything about appears to be factory. And now i read about another one with a 20in barrell, i am starting to be convinced that these rifles are definately special order rifles. Maybe someone can shed some light on this, i would certainly like to know more as none of my reference books help.
