Yeah if that one doesnt turn out to be 14ft, I would call and try to have it confirmed that there isnt any larger out there and see if yours are indeed the biggest.
It would be neat for them both to be record holders for Argentines in captivity

Like I've told so many people on YouTube snakes never stop growing so the size they are at now really means nothing as they grow each time they eat a big meal and shed.
I sometimes wish they weren't so darn huge but I love them the same regardless. It's just way too much an effort and struggle to take them out because I have to force them to come out of their cage condo LOL
I miss being able to handle them alone ;O(
