So I finally decided to cave in and start this wonderful period.
All it took was 5 seconds to see the Carlist Uniforms and Berets and my money was parted from wallet

I managed to grab a copy of Conrad Cairns "The First Carlist War 1833-1840" off eBay and have ordered some other material also. Been using some hobby time to research on the period also. There is some absolutely wonderful characters with focus on smaller actions which really appeal.
The initial plan is to paint a small 50-60pt force of Carlists for Sharp Practice rules and then focus on some Liberals. I'm particularly keen on the Basque region forces under the army of Tomás de Zumalacárregui, Ramón Cabrera is also a mighty interesting chap. For the Liberals I will focus on Militia forces sent to keep those regions in check alongside some French Foreign Legion. This is the starting plan anyway....

Very happy with how the two tests came out and have started the process of batch painting.
Initial Carlists are 16 Line Infantry, with some officers and retinue and some Guías de Navarra.
More updates to follow when they are done!
Cheers
Andy
