Parvalux, Part No.: PM8, http://de.rs-online.com/webdocs/12b5/0900766b812b547f.pdf .
It is difficult to find an shop who wants to recondition small electric motors like this. The Parvalux PM8 with 4000 rpm is a usable substitute, both with respect to mechanical fit, electrical properties and function (speed of raising or lowering the lid) . The engine needs minor mechanical adaptation and then is a good replacement, thereby leving the option of retrofitting the original device.
Moved from California to Florida. They do excellent custom work and can perfectly duplicate the diamond pattern upholstery used in the early Lamborghini engine compartments.
Henk van Lith (HVL) has a company that advertises a supply of original pattern leather and other interior materials for vintage exotics like Lamborghinis. Pricey but appears to have the right materials for a quality restoration. JPR
