who knows this font?

Olde English  Suggested by tophy52 

i know the logo looks like a mix of Fette Gotisch and Fette Fraktur. but the J is different.

You're right for the 'oell' and 'rti' part with fette Fraktur

J and O based on Olde English, fatter
or Mariage

yeah you're right. should be a custom made J based on Mariage/Olde English.
thx.
