I didn't want to started a new thread since this one already has some great information in it, and since the title indicated LB as well it seemed to fit.
I was just going through and comparing my weapons and noticed a difference in the number stamp for two authentic Rainbow Sam lasers that I have. Anyone know anything about this? Based on all other comparisons I'm confident that neither is a reproduction. Were the numbers stamped differently for the US/Japan releases of the lower 12 LBs? This is my assumption but it's pure speculation.
Had the exact same thing a couple off days ago while I was packing up a complete Rainbow Samu figure who was about to get transfered. Its a genuine weapon and it might have been the one that came with the Rainbow Samu missing white eye variant, so in case you do have that figure and that's the gun that came with it it might explain a lot. Looking at all the other weapons amongst the LB its nothing that's occured more and since the missing white eye Rainbow Samu is the only 'accepted' variant amongst the LB it might close the story.
Already packed mine up but I still have it here so I guess I'll take it out and trade it for a normal stamped one because this might just have been the info I needed to get these thoughts about it clearified.
