Lbt Hrb Swrya Llandrwyd -

I notice that the phrase doesn’t appear to be in standard English, nor does it clearly match another common language I can identify. It looks like it might be a typo, a cipher, a made-up string, or possibly a phrase in Welsh (given “llandrwyd” resembles Welsh place-name patterns, like Llandrwyd or Llandrindod) — but parts like “lbt hrb swrya” don’t immediately correspond to Welsh words either.
