Parts Manual 1975 Bombi
--------------------------------------------------------------------------------
I just scanned the parts manual we got for our 1975 Bombi. It is in DJVU format to decrease the size. You can get the djvu viewer for windows at
http://sourceforge.net/projects/djvu...Libre_Windows/It is open source and free. I will be uploading the manual and sales brochure as soon as they are scanned. All files have been OCR'd so that the text is searchable
Since i cannot get an attachment to upload to the forum it is available at
