Cavalry - initial thoughts?

PA are planning to bring out some 'heavy cavalry' in the not too distant future -  the sculptor is working on them at present. The designs are at a very early stage, this post is really to get some feedback on our initial ideas.

Troop Types

For the initial range PA are aiming to cover cuirassiers and dragoons (inc.horse grenadiers) for Prussia, Austria and Russia, and for each provide an officer, standard bearer, musician and trooper. By using multi-part figures this can be done without the need for 24 moulds!

How many horse types will be needed?

Historical saddlecloth shapes

After a lot of searching of books, plates and websites it is clear that there are quite a few interpretations of what was used, however the details shown on 'Project SYW' seem to be a fair representation. There appear to be four basic shapes needed?

1. Prussian Rounded

All Prussian cuirassier regiments except 13

Prussian dragoons regiments 1, 2, 3, 4, 11, 12

2. Russian Rounded

All Russian regiments of cuirassiers and dragoons.

3. Prussian Square

Prussian cuirassier regiment 13

Prussian dragoons regiments 5 to 10

4. Austrian 'Square'

All Austrian regiments of cuirassiers and dragoons had a square saddlecloth, which in many illustrations is shown with rounded corners.

What to produce???

PA are only going to produce a limited number of moulds, so there are going to be some compromises to be make.

Currently I think the initial range might include four sets on moulds, basically:

1. Prussian cuirassier (round saddlecloth)
2. Russian dragoon (round saddlecloth)
3. Prussian dragoon (square sdaddlecloth) 
4. Austrian cuirassier (square sdaddlecloth)

And from these the Austrian dragoons and Russian cuirassiers can also be made, as can a lot of heavy cavalry from other nations.

Any thoughts?
