I know this is no place for serious questions, but what is the easiest way to discern a the two runs of reproduction Fathom playfields?

I know that the first run of 100 playfields by Halifax Pinball was their first playfield reproduction and was a learning process. I've read that the wood wasn't quite as thick as the originals, that some of the art was sourced from the prototype and may not be aligned just right. I've also read some disputes about the color of some of the inserts. And I've read that the clear coat was thin and left a little to be desired.

I've gathered that the second run is the one to get... but how do you distinguish the two?

Thanks!
