Seems you can only get it with the newer ironing boards. That's a shame. I still have mine and I'll never give it away now since I can't get another one. It's a life saver when pressing full widths of fabrics and you need the entire board to press on. I added a 2x4 covered plywood over my regular board to give me a more rectangle surface and I love it plus it's the same height as my cutting table so when I'm pressing large lengths of full width fabrics, I just move it near the table to lay the pressed fabric on instead of allowing it to drop behind the ironing board as my kitties think it's for their enjoyment to lay on afterwards plus the kitty hair.
Hope you're able to find one.
