I've just completed three gun crews and two guns (the third gun having been painted some time ago) for my Britannian, Gallian, and Kreis Obere-Sachsen forces.
First up is a Britannian 6-lbr and its 5 man crew. The gun is a Miniature Figurines (if I remember correctly) model while the gunners are RSM-95 figures. This is the second 6-lbr for my nascent Britannian forces.
Next up is a battalion gun for my Gallian forces. The gun is a "Scruby" (now manufactured by Historifigs) small Napoleonic cannon which will be playing the role of a "Swedish" style 4-lbr. The crewmen are RAFM French gunners painted as two artillerymen (in blue coats) and two artillery laborers (in grey coats).
Last is a battalion gun (another "Scruby") for my nascent Kreis Obere-Sachsen forces (one of the Reichsarmee circles). The gunners are Miniature Figurines SYW French gunner figures. The one of the right rear has been modified by cutting off the lintstock and gluing on a lever. The color scheme comes from a Reichsarmee gunner's uniform posted some time ago by David Linienblatt of the Not by Appointment blog.
I also thought that I would include some side-by-side pictures of the RAFM, RSM, and MiniFig gunners so you could get an idea of their comparative sizes and hefts.

You can see that while the RSM gunners are a little taller than the other two, they aren't completely out of scale. I cheerfully use many different manufacturers on the battlefield and once the action starts, the differences tend to disappear.
