Nobody knows ?

I see every lug has this three-leaf clover type of cutout, not the classic Colnago spade, but similar. It's also on the inside of the fork legs, but the crown has a different symbol (4 leaf clover or stylized cross?)



Here's a website with some lug cutouts listed:

lug symbols...a list nucleus|Bike Club

I see several listed with the words "club" or "clover" for their lug cutouts. I did a quick image search for clover lug cutout and saw several, two that come to mind are a couple of Mercians (although I wonder if they'd use Columbus tubing - Reynolds, no?) and Davidson.



But I didn't spend a lot of time. That's about all I know! I hope someone can help you, I'm curious too.
