Question on Apeks 1st & 2nd Stage

[USMC_Recon]

Quick question for someone on here if they can help me. My friend got a Apeks XTX Tungsten and he was asking me if the 1st stage and the 2nd stage was the same for the serial number. For what i've seen with all the other regs and 1st stages that I have used I have never seen the 1st & 2nd stage with the same serial number. When he actually showed it to me they were both the same unless I was looking at it wrong. Can someone tell me if this is true with the Apeks 1st & 2nd stages regarding serial numbers. Thanks.

mines have the same serial number aswell. First stage, second stage and the octo. all three.

Ok I thought I was looking at it crazy at first. I know that the octo has a different serial number just because they don't make a set of 3 with the Tungsten. Only with the XTX 200 maybe that it why. Thanks for the info.
