The model I'm looking for is the "4Sevens Quark X 123-2 Tactical" or the "QX123-T2" on the barcode sticker, also interested in any Quark parts, or any "V" variable Sunwayman.
So the Maxtoch Owleyes W Pro, although using 2 emitters beats this in throw now and is publicly available... it's around 900lm vs the W50's claimed 1400.
Still looking
Quark 123^2 TACTICAL with XM-L emitter with 360ish lumens before the super short run time 500lm for like 30sec mode for the highest level came out.
Bump, sorry I disappeared for awhile, cash in hand, seriously looking.
Also I should say I might take a Turbo X for my collection but I am mainly looking for the non turbo and it has to be the XM-L/XM-L2 version and tactical UI.
