There are a couple of ways to pronounce the letter ‘H’ that could sound like ‘age’; one that keeps a soft ‘hah’ sound before ‘aitch’ and one that drops the soft ‘hah’. Both can end up sounding similar to a cross between eight/age depending on how clearly you enunciate.
Edit; Age also has a sharper ‘tch’ sound when spoken in those accents. There are probably accents that use a softer ‘g’ sound
I fell under ‘wee English fella’. I was the de facto stage manager at my high school and all the crew called me grandpa or gramps ¯\_(ツ)_/¯
There was also that time I wore a turtleneck/blazer combo so even the cast was calling me Captain haha
