Yes, I did PM the cacher who made the log entry relating to dropping a TB, with no reply. I also PM'd Plumbguy who kindly sent this reply.
" Hi , thanks for the message , at present the tag should be in cache https://coord.info/GC4Y730
I can't tell if this is near you as I only have my phone to hand as we are staying in Portugal attending the Mega event at the moment !!
If it is relatively easy for you to reunite the laminate with the tag that would be great , if not don't worry too much , but thanks for trying "
so I still have the laminate in my possession. When I checked, GC4Y730 had no TB in its inventory, and I could not work out an identity from the Past Trackables list.
Thanks again for all your help.
Edit. I can see it in the list now, but must have missed it earlier, or checked before it was logged.
