The Drop,
Just because the a/c was mfr as a 550/551 or an STC conversion, it doesnt mean that everyone in the world knows what a 551 is.
A 550 type rating is good for both - and if its on the n-reg then poke your JAA rules.
Unless you fly them on a regular basis, do some research before you start mouthing off about illegal flying / operations.
