Here's what I could dig up.
Im my photo above, the forks are (from right to left):
199X DHO
1998 Boxxers
1999 Boxxers
1999 Boxxers
2003 Boxxers
200X DNM's
There's photo's floating around of 1996 team bikes with duel crown Rockshox forks such as this, which I'm assuming are DHO's:
I know the DHO lowers could be swapped out with the other single crown Judy models to give you a 20mm through axle singlecrown fork (I had one back in the day) Lopes and the other RS sponsored duel slalom riders ran that setup in ~96-98
I did find this image of Palmer's Intense dated 1995 with the DHO's
and Palmer's 1996 Intense with presumably DHO's also.
Brian Lopes' 1997 Intense with the new team issue Boxxers. As Alex mentioned, bolt-on arch, but similar colour scheme to the DHO's and the 98 Boxxers (but without the world champs rainbows).
Kirt Vories 1997 Yeti DH-6
The forks on the DH-6 in the 1997 Yeti Catalog are DHO's without the boots. The dropouts are different to the Boxxers.
The forks on the 1998 Straight 6 and DH6 in their respective catalogs are the 1997 variants.
1998 Yeti DH6 with 98 boxxers (note the rainbow stripes on the front) and a moulded arch.
1999 Schwinn Straight 8 with 99 Boxxers
Year 2000 Santa Cruz Super 8. These also came in black.

In 2001, RS went to the candy apple/ cherry red forks.
But... none of this is helping OP to source a set of forks lol.
