I also used one of these in a Gitane TdF (way way BITD) and had no complaints about it when installed. When it came time to remove it (not sure why) I had to take it to a shop cause my tools and/or experience with alloy French BBs were lacking. There's a good chance I still have this in my "bin of ancient items".
If you really want one I could go searching, I'm sure mine would be in better shape, but I would not sell it "super cheap" since it has sentimental value.
I would sell it, tho. I'm not all that sentimental!
WHOA! Hang on I re-read the OP's post and did not realize there were 2 versions of these Stronglight Competition BBs with sealed cart bearings and alloy fittings
One was a 650 and the other a 651; the OP has the version with TI spindle; I most probably have the version with steel spindle (if I still have the one I remember)...
but FWIW I never have been all that impressed with TI spindles (in other brands of BB units). It's a fussy metal that doesn't play well when mixed with other metals, very prone to galling and yes you really need to use anti-seize! IIRC it's even reco'd to use
nickel anti-seize rather than the more commonplace
copper-based stuff, but I may be mis-remembering that detail
