The TR1800 and TR2000 of the 1940's has compression springs but they don't
work quite like you described, they just assist in raising the top which is
permanently installed.
On my TR3 I did disconnect the rear bow from the webbing so I could get the
top up easier as Randall described. Actually I couldn't get it up (the
convertible top, aka hood, that is) at all. However, on a very hot sunny day
when protection from the sun is required, the top would get so loose it
would collapse. My solution was to fasten a double sided Velcro strip to the
webbing and after the top is up, wrap it around the bow.

Are you sure it was the front bow? 

There's an old trick for putting the top up in cold weather, when the vinyl
has shrunk.  You disconnect the rear bow from the webbing that normally
holds it in place, and put the top up with the rear bow folded forward
against the center bow.  That gives some extra slack to get the snaps
snapped, and the dog legs straightened out.  Then once you're sitting in the
car, you push the rear bow back as far as it will go, to pull the top tight.
As it stretches out more (both from tension and the sun warming it up), you
can push the bow back again, to keep pulling the top tight.

I've never seen one that was spring-loaded; my experience is that the bow
will stay in position without a spring (or web) to hold it there.  But that
doesn't mean someone hasn't used a spring while I wasn't looking.
