Rotaryman,
I concur, while many speak of such a thing, a 'low level endorsement' is but a figment of an over-zealous imagination. It's no more than a rating, by no means an endorsement.
I have an entry in my logbook stating that I have a 'Low Level Rating' but it doesn't warrant an entry on my endorsement page!
Anyway, back to the topic, it was 7 months of hangar ratting from completion on of CPL(H) and B206 rating until full time work, but it soon pays for it's self, once the right work comes along.
