This is a bit off subject, but it's cannon-related since it involves the display of my guns.
I've been trying to find some information on the dimensions of wooden powder kegs. While most of my books discuss powder to some length, they all stop short of actually giving the capacities of the kegs and barrels used.
This all started as I revisited some old posts of mine, looking for some totally unrelated snippet of text. I came upon a link to a site that I posted that sold small wooden kegs. These are real oak barrel kegs, in sizes ranging from 1 to 20 liters. The specific ones I am looking at are the 1-, 2-, and possibly the 3-liter sizes. They aren't cheap, but they aren't outrageously expensive either. 1-liter barrels start at $27.99 + shipping (a $3 increase since I originally posted the link). They're cheaper if you buy more than one, and they have special pricing on some combos.
They would make great display items, but only IF they are close to the correct scale.
A little quick and dirty calculation tells me that, at quarter-scale, the 2-liter keg (7.5" tall) would roughly estimate the size of a 30-gallon barrel. At half the height of the wheel, this seems close to the one image I found with a powder barrel and a cannon in close proximity.
The 1-liter keg is an inch shorter and about a half-inch less in diameter.
BTW: As I stated, these are actual working kegs (comes with a spigot and a stand) that are charred inside. I thought I'd put that out there in case anyone has any, ahem, other purpose in mind...
Any information on the capacities or dimensions of actual CW period powder kegs/barrels would be a great help here.
