You were not deceived. Red Eye was suggesting you contact, and hire her. Not that she'd have patterns to share.
Cordula is not a classic Battlestar Galactica fan with Baltar costume references, patterns, etc. to email out. She's is a freelancer for hire as shown on her site.
She is a VERY skilled seamstress who could make the Baltar costume if you provide references - and pay her to develop a copy.
She did Centurion under suits for myself, Red Eye and some other BYC members. She also did an AMAZING job on Red Eye's I.L. Series robes.
Try to contact her again. Send her some images of the costume and ask for a quote for her to develop a copy. You could save costs providing fabric to her, if shipping to Germany doesn't out weigh the price of fabric she could supply. Either way, keep in mind it won't be cheap to have a custom one-off costume created, don't be shocked by a high quote...
Quality work commands a quality price.
Hopefully she - or another source - can get you a Baltar suit... cause that would be AWESOME and everyone will envy you!
Good luck - and please keep us posted.
