Like the poster above says, the old International F was 2-2-2 on MD-11/L-1011 aircraft and 2-1-2 on 767 aircraft.
The actual pitch and recline in old F was less than it is in BE. BE has 60" pitch, whereas the old F had 55", so you didn't recline as far or as flat, but overall I thought the seat comfort was comparable.
The service in old F was generally outstanding. The best F service I have ever had was in 1995 LAX-HKG. Nothing before or since has beaten it; a crew of three working a cabin of 18 nonstop for 14 hours or so, gracious and attentive the entire time.
The old F menu and particularly the wine list was so far better than anything on Delta today that it's sad. Caviar was a mainstay, served with an abundance of garnishments.
On the ground, there was very little, if anything, special done for international F passengers. I always thought that Delta did a miserable job marketing international F and that this was part of what led to its downfall. There certainly wasn't a problem with the service in the air; in my opinion, it was superior to BA (or AF or Cathay).
To this day, I think it's a product that should remain in the mix. I think the solution should be a small F cabin one row across with one flight attendant, with highly stylish and attentive service, both in the air and on the ground. If you sold just one seat in F on a flight it would justify the cabin, and if you encouraged two people to buy C so they could upgrade to F, rather than buy Y so they could upgrade to C, you would justify the product as well. And all you'd be giving up would be two rows of coach seats, more or less, to create a one row F cabin on widebody planes. Which means that, unless the flights are packed, you're really giving up nothing in terms of coach revenue.
