jeffa, I have doubts (as does scorpiojo). I really like Warrant Card but I've never known this quiz setter to give out an erroneous clue.
I will apply the frazzled, quizzled brain cells tomorrow if I can find them. It's already 1:30 a.m and Smart Card is looking more and more attractive :))
Hi all.
Thanks for your thoughts, 1ozzy.
As soon as I'd shut down my PC last night, I thought of "radar trap".
Used by the police to identify speeding vehicles, so I have hopes for this solution.
Thanks again for your help.
