Wow, you've got some beautiful 33s in your pictures, 33 is my favorite pattern. I don't see any 27s in your photos (granted I haven't been thru all 925 of them). The 27 is similar to the 33 with rounded bolsters... I try to focus on the smaller Case patterns, especially smooth handle models. (something about Jigging turns me off)
Beautiful collection. I tried to get my wife to look at them with me last night, but she could not care less.
