[Halvor (Raknes)]

I have in my possession a copy of this edition. In the colophon it has a printing history:

Simon & Schuster edition published June 1962
2nd printing .... October 1962
3rd printing .... March 1973

Bantam edition / September 1973
2nd printing .... April 1974
3rd printing .... October 1974
4th printing .... July 1975
5th printing .... March 1976
6th printing .... August 1977

This edition appears to be the first Bantam edition, so perhaps it should be merged with the edition pinned to the topic?

And perhaps the year should be changed to 1973 with the iterative printings listed in the 'edition' field?

I don't know if this is prudent because I'm unsure whether the ISBN would remain the same through a succession of printings.
