Specialized Vegas Fatboy Question
 

Hello All,

I recently was given a bicycle from a friend and it is a Specialized Vegas Fatboy, at least that is what all the stickers indicate. My situation is that the bike is in sad shape. It needs every thing replaced. Now I am willing to restore the bike and give it to my son. Problem is that so far in the last week I have seen 6 different versions of this bike.

Specialized Vegas Fatboy TRX
415 PRO
415 FSX
415 FSX Expert
TJ
Fatboy Vegas
Other then the stickers stating "Vegas Fatboy" are there any other determining factors that could indicate what this bike is ? I only have found next to the serial number the letter V stamped into the bottom bracket metal. These are the only markings I have found. The original color is an Olive Green if that matters. One more thing, since pictures of this bike seem to be very limited for some reason I was able to eliminate 4 of the 6. Just by looking at a picture from the internet the bike I have now looks very much like the TRX and the TJ. Frames seem to be indentical so, any sugestions on what bike I may have? Thanks for any information.
