73 with original fabric?

[JimParker256]

I'm looking at a 1973 ECA with the original factory-done fabric. It appears that the fabric is otherwise good (at least thus far in the process). What was the factory using at that time? Would there be a rejuvenator that would work with that process?

Jim:

They all used Randolph dope after the 1950s. Results of rejuvenating dope has been very spotty and even if successful, will look like s**t. 42 years is too long to go without a good inspection of wood and steel and pulleys under the fabric. I recommend a recover.
