I found out these are XR forks after all. Previous owner must of upgraded to them. I found out when looking at the drawings of the sliders on CMS, plus they just seemed too long/too much travel to be XL forks.
I pulled one apart to measure in MM
slider from axle hole to top - 355
exposed chrome (from top edge of slider) fully extended - 581-582
exposed chrome (from top edge of slider) when fully bottomed - 333-334
total length of fork extended (axle to top of inner) - 936 - 937
travel in mm - 247-249
travel in inches - 9.724 - 9.803
damper rod length from under the piston/head to base is 305mm
total tip to tip length of chrome inner rube is 752mm
Fork caps have ugly external damage but i got some DG caps that fit these forks.
