This is the first of another of the Beeb's "time travel" series, this one concerned with a small village bakery turning out fewer than 200 loaves a day. Check the size of the oven they're doing it in, wow! Other equipment looks familiar, like the big troughs for proofing dough, things I saw in the 70s when I was doing nutritional labeling for a big commercial bakery supplying the entire northeast.
In any case, it's a fascinating look back. Episode 2 is at the site on You Tube, just click the title of this video.
