I cannot find one for my Bavaria, I assume those for the e12 or e24 may interchange, anybody have an alternative?

Hi Bob.
This may be a stupid question but are you looking for authenticity or just functionality? If you just need something that works, there are hundreds of Dryers that should do the trick and of similar, if not identical, size, provided you get the correct fittings (most of which are AN 6 I think). If you need a link, I can indicate where I purchased mine.

Try this Mercedes number it's a match 115-835-04-71
Drew,I am starting to redo my AC and not worried about original parts but actually Doug's info is spot on (great to know BTW) as the images look identical to the BMW NLA drier..and for 25 bucks no less. Awesome!
Luis,
I assume you still have flare fittings as original for R12? I think O-Ring fittings might be different and require another drier but I am not sure.

Another question. I am second owner and I believe all the ac mechanicals work and there is just a leak to find and then an R12 charge. I have that monster four seasons compressor. I would use the AC maybe twice a year. For the little I use the car, should I keep the thing?
"Just a leak" in an original system could be like "just a little rust" in a coupe... It may be several leaks.
By "monster" you mean the original York compressor? If it was my car I'd check for leaks with nitrogen and then go from there. If the compressor itself is leaking, then I'd replace it with a modern one. I know some people would, even if the York works. The connections could be redone with fresh (cheap) copper washers and see if that corrects the leak(s).
I've not owned a car with a York so I can't speak to its cooling power and noise/vibration but I have to believe the newer rotaries (a la Sanden) are far more efficient and rob your engine of less HP.

You can buy a kit and convert to a rotary compressor to replace the old York piston type. The kit is actually used on later model m30'd i.e. 5, 6 & 7 series cars.

Two Different Approaches
The longest single chapter in my book is on a/c, but to summarize:
If an a/c system is functioning, it is not leaking (or leaking extremely slowly), and no components need to be changed.
If an a/c system is NOT functioning, then something isn't working. It could be a hose has a leak, or the compressor has s**t the bed, or the expansion valve is plugged, etc. But the fault must be found and, the system must be leak-tested, and then recharged. Whenever a system is opened up, the receiver dryer must be replaced. I assume this is why the original poster is looking for a replacement.
If the hoses leading to and from the dryer are leak-free, and if the system is being recharged with R12 (which is what I'd recommend), then the quickest and easiest thing is to use the recommended Mercedes part, as it has the same flare fittings as the original hoses.
If, however, the hoses are bad, and/or other major components like the compressor and condenser are being updated to improve cooling function, these things necessitate having new hoses custom-fabricated. If that is happening anyway, it makes sense to switch from flare fittings to O-ring fittings, and if that is the case, virtually any generic receiver dryer with O-ring fittings can be used.
I have these two different approaches at play right now. I recently did an a/c rejuvenation on my '72tii where I updated every major component except the evaporator core and crimped every hose myself. As part of that, I switched from flare fittings to O-rings everywhere. However, I just bought a Bavaria that is so original that, as I sort out its a/c, I'll try to change as little as possible and thus will order this Mercedes part.

Rob, A) You are ahead of me on the curve and B) I tell my kids to learn from the mistakes of others. Hence, once you have discovered and dealt with all the Bavaria AC demons, I would be more than happy to buy lunch and listen.
Seriously, my ac does not blow cold but all seems functional and I know there is no R12 left. I think another scenario can be "slow leak, PO let car sit in a garage for 6 years". I will pressure test to start and R12 it will stay.
