Nice terraplane style fork that has a shock absorbing profile with canti mounts and obvious fender clearance (would prefer a mid fork rack mount, but that's the tourist in me...)
Reasonable clearance on the stays yet not so long that flex is an obvious issue
Standard size fork/wheels
Seems to split the difference between sport tour and tour geometry
Proper bridges and rack mounts, yes

Don't care for the pseudo-lug thing on the headtube, but no performance penalty there...

For a modern production frame, there's quite a bit to like in that. Looks stable and fairly comfortable on gravel and fire roads, which is a plus for you. Priced a bit, but if it's what you want certainly not too high.

Would look awfully nice with a 90's campy triple crankset on it pushing an 8 speed close ratio rear (covering all your bases).

Them's my thoughts...
