Ah... I cannot see the details that you can as the photo is not the best. There are only two plates for this stamp and ,as you have very quickly learned

, there are flaws that can identify the plates. The
TW joined flaw only affects certain stamps in a sheet of 240 of plate 1. I'm not sure, from your photo, of the check letters on your stamp. As always, detail is always a help to identify so, from what I can see, I can definitely state your stamp is either plate one or two
