'74 450SL A/C hoses

Looking for the Evaporator to Manifold A/C line for a '74 450SL that the previous owner converted to R134. Any chance of finding a compatible hose (i.e. barrier hose)? I have been unable to find the original MB part number. Does anyone have a part number for it? I'm guessing that the original MB hose was non-barrier. But maybe someone is making a modern one.
Thanks in advance.

I had my hoses remade in modern barrier material; sent them the old hoses and they made up replacements. I used these guys: https://coldhose.com/hose-repair/

Note - the new hoses are not identical in appearance/outside diameter, but they do fit. In particular the hose from the evaporator to the drier was a larger diameter.
