Re:
Have you thought about a snowflake lacing pattern for the wheels? That was a period correct trend for this bike and a fun way to build wheels. I did it on my Kona hahanna that I was lacing a wheel for. I started a 3x pattern, but miscalculated the spoke lengths (they were wayyy too long) so I just twisted them round at the final cross until they were pointing at the hole they were originally destined for to finish it off. I imagine they compromised the strength for serious MTB, but I've never broken a spoke using it for commuting on pretty bad roads, even with a pannier on the back.
