The frame and fork were purchased off fleabay....it had been on for about a year with a ridiculous price.
I offered way way low...as it was pimped out as a street bike with a bike cancer/rust disclaimer....they agreed to a price less than half of asking.
Upon inspection it appears to be original including the fork...that I know of...I did some rust abatement inside the seat tube and there are plenty of nicks about the frame that i touched up with a variety of fingernail polishes.
Parts-wise -- I slowly but surely have been buying things here and there on ebay, with the intention of building up another tasty grello that i have.
I think by and large it is fairly period correct...
it rides wonderfully.
I am a little leary of the rust issue...but I think i will ride it until it fails -- and then beg rody or igleheart to consider the work.
meanwhile it will sit in a heated dry/finished basement shop...
A queen yes...but what a queen.
It will be a stable mate with a variety of other collectables, including 1980/81 original Ritchey MTB.
Since the SN indicates your frame is a 1991 model, it was built at the old Olive Square shop in Somerville, MA. It's a YO so most likely, I welded the frame. The head tube and the seat tube both have welded inserts. It's good that your fork has the brazed tear-drop gusset plates on the back of the tubes. Those gussets are critical for maintaining longevity. We found out (the hard way of course) that failures were occurring and Chris came up with the gusset idea. We tested several designs and came up with the tear-drops which were laser cut from 4130 straight gauge tube. They were brazed with silver alloy filler and I think the added brazing step also helped to stress relieve the welded crowns. Check these frequently, it is still possible to have cracks develop at the tip of the gusset, especially if you do a lot of jumping.
Another area to check carefully is the chin gusset at the down tube - head tube connection. The gusset extended the fatigue life of that joint by over 5 times but failures can still happen and that is the most highly stressed connection on the entire frame.
Best of luck with your YO. Take care of her and she will take you places you never thought possible.
Unless my eyesite is really far off I'd say that's a BOI fork. If so I don't believe they were available in 91 or perhaps a special order/substiution early production fork for the 10th Anniversary model.
