Ireland Stamp With Holes

I came across this one in my collection. It's either Ireland Scott 65 or 106. Haven't had much luck with the Ronsonol yet with the watermark to figure out which it is. Anyway, here is what it looks like from the back. I have this as an attached pair and was going to show the full picture both front and back. Then I saw the 200KB size limit. So this was what I was able to come up with to get under that size limit. So what do these holes represent? I tried looking online for some explanation but didn't get anywhere with that. Any help would be appreciated.

Perfin cancel. See the Glossary under Navigation in the column to the left hand side of the page for definition. Perfin. Perforated Initials.

Your perfin is LSS/Co (Limerick S/S Co Dublin)

Thank you both for the information. That PDF was very informative and I plan on saving that for future reference.

Thanks again!

Maybe from the Limerick Steamship Company?

Here's an excellent video giving an overview of perfins. I honestly never knew what the term was short for until I watched this video! It's only got 9,900 views in the last 30 days :)
