Doubt you're going to get a lot of hits on a foreign coffee machine that's 60 years old. But I did notice that there's a reconditioned one being sold on ebay. (The seller was the reconditioner.) Why not write Ron, tell him you have one of these machines and ask if he can help? You'd reimburse him for his time of course.
Anyway, just a thought.
This is an original 1965 E61 with original front, back and sides. Manufactured 19-10-1965. The steam wands and water outlet have been replaced. Parts were sourced from Rebel Espresso Parts in Rocklin, Ca.
