Hi Tom,
I understand and agree with you.
My initial surprise comes from years of personal experience in complex manufacturing, where each discrete part was controlled through the process with an identifying number that set it apart from all others. In this example, the butterfly (sub-assembly) frame casting has a number that tells us more about its origin:
901.613.805.0 Click to view attachment Obviously, the manufacturing team felt that there was no need to assign a separate, unique number for a relatively minor item that could be controlled in another way. Even though, depending on with whom you are speaking, the finished parts are technically not interchangeable.
Good discussion. Thanks for engaging.
Cheers,
Wayne
Wayne,
Usually that trailing xxx.0 is the defining sub-part number, with .0 or .00 being the first in the series, so that above pic makes sense, & maybe the Porsche Crest butterfly is/was .1 or .01.
They did a similar thing on the 914/4 4-lug wheels pre-73 non-hubcentric were ending in xx.00, & `73-76 were xx.01 for hubcentric
At least you have confirmed for your sale that it's the Euro/ROW one, for anyone looking to restore a 914/4 from those markets.
PS - More of a conundrum is that the 914 PET Parts Manual lists it as #31 on Illustration 403-05 as p/n:
914.613.805.12 - whereas yours is p/n:
901.613.805.0 which is an early SWB 911 p/n - so perhaps it was an early 70 914/4 until they got 914 versions .... or perhaps somebody had it recovered with the Wolfsburg Crest from an older 911 - not sure anyone can know at this point.
GLWTS!
Tom
