Hey Lads

I apologize ahead of time if this is rehashing something found elsewhere on this forum - but this forum is rather
large and I wasn't able to nail it down in my search.

Though I claim Clan Lamont, recently I have been doing research on some of the other many amazing tartans out there
and in my searches I came across a very handsome yet (I think) understated tartan called the Grey Watch. I could not find all that
much concerning it, but can I assume that this is one of the so-called 'universal' tartans which anyone might use?

Thanks in advance for the info!
