Firstly, the statement in LASORs is only relevant to the UK not Europe. Secondly, when introduced it was intended that this would provide an allowance for persons who had started training in one State and then moved to the UK. UK Service personnel being a prime example. It was not intended to allow people to flit between States doing a bit here and a bit there, hence the reason to contact the CAA to see if the experience is acceptable.
JAR-FCL says you will get a 10 hour credit for your flying, you will have to complete 25 hours dual with a JAA FI and pass the exams and Skill Test. Most RFs in Europe will offer the training and exams in their National Language.
With 50 hours dual and 1 solo, I suggest its going to take you another 50 hours so any credits are probably irrelevant as you will effectively have to do the complete JAA course. Maybe you'd be better off finishing where you are!
