Hey Thanks, the only german I know is my last name (Reitmeyer).
I'm not sure how I would arrange shipment. But I do have a fax number 707-929-1766. Also, you might see if you can get an international efax.com fax number, this makes a fax an emailable file automatically. I don't know if you can get a local to him efax number?? I'm not sure but they used to give efax numbers for free.
No problem with pay arrangments if someone can vouch this guy will follow through with the kit. No problem building a Jet without instructions, my isobar thread is evidence of that
