Robert,
I have an 1894 BE #132102 and it is the standard action as pictured. According to Semmer's book, my gun and your lowest improved gun(#132790) were both built in 1905. Hope this is of interest to you. I'd just like to add that Semmer's book is worth every penny to Remington double addicts as are his DGJ articles. I don't own any 1900's to compare, but your guns date as 1902 and 1907 according to Charles.
