AC decal part number

[Bob G]

I am sure this post does not belong in this area. however since most of the best technical people visit this forum I would like to ask a question regarding the small AC tag that goes on the plastic support bracket to hold the air cleaner hose.

This little decal when it gets wet or heated comes a part. the purpose of this little tag is to tell the technician how much R-12 goes in the AC compressor. What I need is a part number off this red tag.

I am hoping some of you have a pristine 1992 300E that this tag has not been destroyed and is readable. I contacted the Mercedes-Benz dealer and they said they needed a part number for this small red tag.

I would appreciate the help as I am scouring ever were to fine a pristine
300-E with this tag still in place and readable. what is sad is that this tag is made of paper and prone to damage the first time you clean you engine.

Thank You for your time.
