If you have something which is not a tractor and not a car we will have to search the very disorderly archive, find the documents (if we have any), assemble them into a PDF, watermark it and get it to you. All this takes time so there is a small search fee. This will be deducted from the cost of your manuals.
We do not do cars. There are other sites for Gutbrod car owners, try searching Google.
