Thank you very much to everyone for their kind comments.
In answer to Miquels question, yes the Waterloo project was dismantled in order to make way for Ligny. At the end of the re fight, Ligny will be cleared away for Quatre Bras.
The retreating Prussians you mention are from Art Minituran and are not conversions.
The project benefits hugely from the large scale use of Hat figures as this keeps the cost down. Other manufacturers and the use of many conversions fill the gaps.
