Hi all. Picked this up over the weekend off craigslist. Can anyone help identify this frame? The bike came with a mix of shimano and suntour parts. Araya 26" wheels. Tig welded frame. Blue appears to be the original color of the frameset. Two sets of water bottle eyelets on the downtube. The bars are these fillet brazed bullmoose bars with SPECIALIZED and MOUNTAINBIKES stamped on the stem. Im thinkingfrom some searching around that it could be a Japanese Ritchey. Serial number reads T4J82691 and has <EO> stamped as well. Any thoughts?Help identify this vintage MTB...fastback...tig welded??-img_20180827_160837051.jpgHelp identify this vintage MTB...fastback...tig welded??-img_20180827_160852382.jpgHelp identify this vintage MTB...fastback...tig welded??-img_20180827_160903405.jpgHelp identify this vintage MTB...fastback...tig welded??-img_20180827_160910206.jpgHelp identify this vintage MTB...fastback...tig welded??-img_20180827_161118423.jpgHelp identify this vintage MTB...fastback...tig welded??-img_20180827_181907098.jpg
