Anti-siphon valve?
Would a 1977 2500S fuel tank have an anti-siphon valve factory-fitted? I'm thinking a fuel transfer pump might be the cleanest and safest way of draining the 10+ year old fuel from my tank into a jerry can but don't want to buy one only to find I can't use it...

No, the filler goes straight into the tank. Easy to siphon.

Re: Anti-siphon valve?
The easiest way I've fount to drain the tank is to break the fuel line at the rubber hose where it appears at the end of the gearbox tunnel, quickly (before you get too much fuel on the drive!) connect a length of rubber hose out under the car to a jerry can by the front wheel. That way it's all done by gravity and drains to the lowest point on the tank.

Re: Anti-siphon valve?
If you have good access under the car or it is on a ramp, then an alternative would be to disconnect the union on the underside of the tank above the diff. It is offset, so that access is reasonably good. The hole for the fuel to drain out of is then bigger than from any fuel lines, so the old fuel will come out quicker than a fuel pipe and any crud that might be in there has a better chance of escape. You can also pour another gallon in as quickly as the neck will allow to help remove any sediment from the tank. If you slacken the float on the side of the tank, without removing it fully, to allow the passage of air, it should allow any flushing fuel to be poured in quicker.
I have always drained Triumph tanks this way.

Remember a jerry can only holds 4.5 gallons.
