What is this sticker?

I was disassembling the dash of my 64 230sl to get ready for the installation of the radand as I was tidying up inside the dash I found a metal plate that was hanging to the portion of the blower (at least that's what I think it is) that faces towards the dash.  I've attached a photo of the small metal plate.  Does anyone know what this is?

Interesting. I have not seen that plate on the Pagoda. BEHR is usually related to the cooling/heating system.

Indeed it is the ID plate with part number for the blower motor.

Thanks.  Are these numbers unique to a specific car or are the general part numbers?

I am not quite sure what you mean with "unique to a specific car".
I assume that BEHR had unique numbers for its products and did not duplicate them.  So in that sense this number is unique for your blower motor (indeed mine has a different number) and your Pagoda but it is by no means something akin to what we understand as a "matching number".  I don't think anyone gives a hoot about whether the blower motor is still original, a factory replacement, or just a correct replacement at some time, as long as it blows air.

In any type of data matching you always try to dertermine a unique identifier. For example, for a car it would be a VIN, for a person in the US a SSN. The reason for asking if these are unique to a car was to try and determine whether the possibility exists to trace this back to an original VIN since all of mine were removed from the engine bay. I have no desire for matching numbers, rather I want to be able to trace the history of the car.

Sounds like you already know the chassis number should be stamped on top of the front RHS frame rail as well as on the type plate, is your stamped number missing?

Yes, missing.  It looks as though when they restored the car in the 80s it was either missing then or they removed it, as that area is now painted over...do you think there is any way to draw a correlation between this number and the chassis and/or VIN number?

[66andBlue]

To get to the location where the VIN stamp should be have you taken the large rubber hose at the intake off and then removed the paint with a chemical paint remover? The numbers are stamped in really well and it would take quite some effort to grind them out.
Only thieves would make that kind of an effort.

The blower number will be of little help. But if the VIN stamp is really gone then perhaps the Classic Center can help you finding it via the engine number. Is that one still visible?

I was thinking of the other stamped metal plate on the drivers side. Going to taka look now and see about the stamped VIN. I should've done my HW and read up some more. Will report back. Thanks

Mission accomplished.  VIN has been determined
