ID Mfgr of Soldering Iron Tips

[shrtrnd]

Have some soldering iron tips, but can't remember which irons they originally fit. They're marked:
WL-3, WL-4, WL-14, WL-16

Anybody know which manufacturer made the prefix 'WL' for their soldering iron tips?

I would have guessed Weller but I don't know. Maybe a picture (with dimensions) could help?

I just stumbled onto this 2 1/2 year old post I made, while I was Googling information.
I'm just answering my own question here now, in case somebody else stumbles onto
it while they're looking for information.
The solder iron tips in question were made by Hexacon.
