Want to trade 8087-6 for 8087-1

[black_monolith]

I have a working gold top Intel 8087-6. I believe it is C8087-6. I would like to trade it for a working D8087-1 (the one without the gold top). Is there anybody interested in this kind of trade? I believe the 8087-6 is much less common than the 8087-1. I am not a CPU collector, but I build vintage systems and I actually use these chips. I currently have a C8087-1 in my 10MHz XT clone (bought from a Chinese seller), but it keeps overheating and I suspect it might be a remarked 5 or 8MHz version. If anyone is interested, I can take some photos of my chip.
