I know he posted to this site a fair bit, I don't know if anyone here spoke to him regularly.
He was a friend of my family longer than I've been alive, just got a phone call today saying he passed away last night.
He loved Glasgow/Yoker and it's history, always had some interesting things to tell me.
He's taken quite a lot of photo's documenting Yoker, hopefully they'll pop up in the future when people are looking for the way it "used to be".
A lot can be found on his Flickr page
