BSAC 220 two or three catapults?

HI

I think Ja Worsley is wrong with three catapults. I have always read that BSAC 200 and 220 should have had two catapults. Three catapults for two dozens aircraft on less then 30.000 tons does not seem probable.
Here is a source for the two catapults:

I think that the second catapult is on the far starbord side. The line of the “middle catapult” could be a safety line for the landing strip.
Somewere I have seen a piture of a Yak 130 trainer mock up with foldable wings – I am sorry I could not find it.
Perhaps this could be an alternative for Brazil?
