Flickr: critical_ear's Photostream

My first post here! I'm trying to find some information on WE 142a and other WE gear pictured in the flickr link above. One of the 142's is missing the 116b amp sections. I'd like to complete it, but wondering how difficult it will be (I'm guessing very) to locate and acquire them. Perhaps I should sell and move-on.

Any advice/guidance on this and value would be most appreciated!
