I think that nostalgia is probably a lot like what childbirth must be for
women -- one forgets the pain.
When I was a student who put on the hat "building contractor" during
summer break, I'd take on one or a few vacation home projects in the lake
country of Northern Ontario as a paid "holiday".
ie We'd work during the week when we had the lakes to ourselves and go
back to the city on a weekend when the people from the city invaded.
One of the vehicles that we often used for the trip back and forth to
civilisation was a 1938 Chevrolet Master Deluxe (same as this one:
http://ipocars.com/vinfo/chevrolet/master_deluxe_town_sedan-1938.html )
Yes, it was pretty nifty to tour around in (at a time when Honda Civics
were just introduced to North America) and one would tend to say "They
don't built 'em like that any more" the reality is that the behemoth
weighed almost 3000 lbs, and only got about 80 hp out of a 3.5 litre 6
cylinder engine and at best, maybe 15 litres/100 kms ( 15 mpg US) if one
was going downhill, with a tailwind and some luck.
And the thing was prone to vapour lock

Sure, one thinks of cruising around in that old girl with fond memories
but the day-to-day realities of living with its ancient/inefficient
technology was susbstantially more rude (ie filled with expletives).
As for the 1920's toilets, my parents' house that I grew up in had one of
those "modern" 1920's era toilets. "Modern" because the reservoir was a
porcelain tank down by the bowl rather than a lined wooden tank up near
the ceiling.
The memories of life with that concraption are less fond. It may have used
less water per flush than
toilets of the 60s and 70s but I seem to recall that it didn't flush
particularly well, often requiring multiple flushes to accomplish the task.
The craftsmanship and materiality (ie aesthetics) may have been better in
yesteryear ( ie the "lost wax" casting process:
http://en.wikipedia.org/wiki/Lost-wax_casting )
but the technology which they employed in order to do the tasks for which
they were intended often left much to be desired (when compared to
today's).
Moral of story : Art and Craft may have been more evident/better in the
old stuff but there is no comparison to operating efficiency of 21st C
technology. And as past discussions re: embodied-energy vs life-cycle
operating energy illustrated, LCOE is far more important from a Green
perspective. But From the "I too will something make ... And Joy in the
process" perspective, products of the Past, win.
The challenge then becomes "Can one take one of those arty/crafty Products
of the Past and adapt them to utilise efficient 21st C technology."
