Auriga has an aluminum boom from Metalmast. I'm not sure if it was a retrofit or came from Pearson. I have an old Simpson Lawrence manual vertical windless and about 200' of chain. I usually pull it by hand as well but it comes in handy when the wind and tide are strong.
I would love to get an active forum going. There is an Alberg 35 Yahoo group that I assume was started by Tom. If you haven't seen it, here's the link: ALBERG35 : PEARSON ALBERG 35
. It's unfortunately rarely active. Tom has actually posted a bunch of updates on his own refit but it was in a corner of the site that was hard to find. Here's the link: 1965 Alberg 35 Tomfoolery - Hull 212
I own a web development/hosting company so I would be happy to set up and host a forum if there is enough interest.
