Need help figuring out this 1969 guitar part (Communication Breakdown)

[MKuznetsov]

There's a really good version of Communication Breakdown on the Winterland tape from 6th November 1969. From 4:08-4:36 on the tape Page plays these two really cool parts on there, I've been trying to figure them out on guitar but it still doesn't sound right. Could anyone on here break these two riffs down for me? The second riff is called "Bert Jansch Section" on bootleg databases, and I've tried listening to Pentangle (Jansch's band) to try and find the potential inspiration of the riff, but to no avail. In this same tape the riff also appears during Dazed and Confused, from 28:47-29:30. The first riff is more often heard on live versions of Communication Breakdown from 1969, but I don't think it has an official name. Here's the link to the tape:
