Looks like a Nippon Denso; Honda Civic CVCC, 1979, no A/C, Lester number 14184:
I (and many 1990's vintage RVs) have been flying this alternator since 1999. It is 35amp, externally regulated, 1975 Ford LTD regulator works perfectly. Don't worry about the fan, either take it off or leave it to rotate the "wrong" way.
Reman is $23.99 (life-time warranty) with core in the States!! Will no doubt be much more in Sweden....
As long as I own the old Honda Civic I can get free replacements.
