The one I found looks to have no tagging on it under the UV light, but it looks like there are still 2 bars on the sides of the stamps. Is this normal, or could it be a OP4 that the tagging wore off of (i can't see it happening but you never know) Also the coast line in the back ground under UV seem to have a glow to it.
Just looking for some thoughts on the subject
Normal under UV light

Possible T1 with glowing coast line
