Well, as a follow up to my question - I bought some guns from Askari. The pair of French 80mm mountain guns, the italian 75mm mountain guns, and a single field Krupp gun.
The positive - these models are exquisite. Well sculpted, very little flash or mould line, easy assembly. Bloody beautiful.
And the service was prompt at a good price. Kudos to the owner - he got these out in the next business day.
The negative - I didn't realize these were true 25mm models. These cannon look like teeny little guns next to my 28mm figures. Will it stop me from using them? Oh, heck no. Does it look a bit odd that some of my figures are carrying rifles with a larger bore than the cannon. Unfortunately, yes.
