Wanted: Ohio Scientific...

For those who don't already know, I focus my vintage collection on Ohio Scientific. I would really like to fill out my collection with a C1P-MF Series II, pictured here (sorry if the URL wraps): http://www.technology.niagarac.on.ca/people/mcsele/images/OSIAd-1981PopularE lec.jpg Also, I need the tan/brown metal floppy chassis for an original C1P-MF. Yes, I know that many were sold with the metal/wood floppy unit that usually went with the C4P but I'd like an example of the other model. Finally, I'd like a better example of a C4P metal/wood CPU chassis. I have a 4P with the electronics in good shape but the case is pretty rough. None of the above need to be working, just in good physical shape. In pursuit of the above, I am considering trades of other parts of my collection that are rather rare. Also, I have a small reserve of convenient, wallet sized presidential portraits (but don't get any ideas of ebay level riches). Thanks, Bill Sudbrink
