Help with signature

[Koll]

Can't be sure of the language but many people have suggested it. I was hoping someone might be able to tell me what it is. I thought it could be Cyrillic as it seems to me that the first letter of the second word could be Ч (Ch, Che or Cha) and I think Ѳ (fita) may be in there too which is old (pre 1918) Cyrillic. I don't know for sure what it is but I'm hoping someone on here can tell me. The photo is all I have. It might not be a signature but it probably is.
