I also think l114. If it were an L600 the spots on the head would be much smaller.
While I'm not sure if I'm correct on this part, it also appears there are faint spots on the outer portion of the middle of the trail. Mine was like that when purchased and as it's grown the spots have filled in just leaving the top and bottom of the trail orange. I'm thinking this will do something similar as well.
Sorry i couldn't get a better angle on my L114. He hates having his picture taken and never sits still. I'll need to take some more, but this should be a decent example for now of what I was trying to describe in regard to their head spots and tails. The base coloration is also a bit greener on the L600, which is posted above the L114. Both are roughly 4"
