Decola or Dicola or both?

Forgive my ignorance here, I've seen both Decola and Dicola cues listed for sale.
Are we talking two different cue makers or is it simply a spelling issue?

Nothing....now i don't feel quite as "cue maker identity" challenged.
The reason I posted this is because someone had this Dicola cue for sale on Facebook.
Segmented burl with an ivory buttcap, joint and ferrules on the two shafts.
The finish has a couple of cracks but according to the seller, only the finish.
I picked it up under those conditions and we'll see if it has any cracks in the ivory or the cue body when it arrives.
If not, I'll get it refinished and have a pretty nice cue for a great price.
