Looks like Chorus. Record had a 4 arm spider of that era.

I say SS it. Beautiful bike. IMHO if you were to sell it, I would part it out. Sell frame/fork and then sell the rest of the group w/ the option of cutting off the rims before you ship. Most folks who want that group will want to build up with new rims and won't want to pay the extra fee for shipping such a large box. The brake hoods look like they are in good shape which is often an indicator of the condition of the rest of the bike.

Not sure what it would sell for, but if you clean it up and take good photographs I don't think $800-900 for everything is unreasonable. I sold a full bike (which I should have parted out) years back for $1200 on fleabay. Full Campy SuperRecord on a classic DeRosa SL frame painted classic red. Looking back I should have kept it.
