PDP-11/45-55 CPU fan assemblies

(No doubt, removed to allow cannabilization of the fans, to keep another machine running.) (For those who aren't familiar, these are long brackets to which a number of the usual square fans are bolted; one is placed above, and one below, the cards in the main pull-out rack of the CPU. The one on top is hinged along the long edge, so it can be rolled back out out of the way, for running cables to boards.) So, does anyone i) have a spare set they don't want (I know, I know, I know, p < .00001, but maybe a miracle will happen); ii) have a set they can lend me so that I can get the sheet-metal part copied (I might get a spare or two made at the same time, depending on price, so we have some on hand); iii) failing all of the above, be willing to take lots of pictures, and some measurements, of a set, to aid in making reproductions. Thanks (hopefully :-)! Noel ========= I have an 11/45 and 11/55. The colors of the /55 are quite different from the 11/45. p <.00001 might need reconciliation ... I would have to check, but I am pretty sure I have the bottom "box", complete with fans. However, I remember it is *heavy*. I could remove the fans, but it is steel metal, so it will still be heavy. Shipping would be from The Netherlands. That is "world shipping" ... expensive :-/ I think I also have the top, but here my memory gets vague. It will be a few days before I get back to my "museum" though. Probably Tuesday evening. greetz, - Henk, PA8PDP
