marin litespeed titanium

I have an old Titanium bike that was once listed as a Marin Team Titanium on ebay (in 2004) From research it looks to me more like a Litespeed Standard Mountain Frame from 90/91. The machined finish on the rear drop out (unusual?), two holes and placement / shape of the four digit frame number...

I am considering selling my much beloved 1992 Litespeed made MARIN "Team Titanium" frame. Note: NONE (!) of the parts of the build are for sale. None! I am parting ways with the frame only. And only because other spectacular projects are on the way to my shop which will be a superb substitute...
