Labels

I'm trying to find out some part numbers for labels on a 1978 450SL.
The labels are located on the radiator support; there are three of them. Mine are all faded and I can't make out the part numbers on them.

Label one is to left of the hood latch as you face the front of the car. It's just above the VIN stamped on the radiator support. I think it's black. It is about 1-1/4" x 6-1/4".

Label two is directly to the right of the ID tag on the radiator support. It looks like it says Automotive Air Conditioner - that's about all I can make out. It looks like it's red or orange. It is about 1-1/2" x 1-1/4"

Label three is right next to Label 2. It is about 1" x 3/4".

I think there is a part number on each one of these labels. Does anyone know what the part numbers are?

Come on, somebody out there pop the hood and take a look for me. The part numbers are on the labels. Thanks.

I would love to but a couple of them I looked at have no labels. Have you tried the Mercedes classic center?

Thanks for your reply. I tried the MB Classic Center, but they have no documentation of what labels were put on the radiator support in 1978.
They told me that if I provided them with a part number, they could tell me the availability. Hopefully, someone can make out the part numbers on their 450 for me.
Thanks again.

I'll look on mine this weekend. The car is stored in a garage about 10 miles from my home. Since the weather is supposed to be decent Friday to Sunday, I'll have it out and take a look. BOB

Label #2 is the one that tells anybody working on your car that you have R-12 in the A/C lines. If it were green, you would have R-134a.
