22MM would normally convert to about 1/72.
I have attached a photo comparing various figures and sizes. Refer to
plasticsoldierreview.com for info about the plastic figures.
From left to right:
1. K&L (formerly Thomas), metal, 20MM.
2. Musket Miniatures, metal, 22MM.
3. Airfix Wagon Train, plastic, 22MM.
4. Imex Confederate Infantry, plastic, 24MM.
5. Imex Alamo Defenders, plastic, 23MM.
6. Esci Confederate Infantry, plastic, 24MM.
7. Strelets Confederate Infantry Standing, plastic, 23.5MM.
8. Italeri Union Infantry, plastic, 24MM.
9. Accurate (Revel) Union Pioneers, plastic, 25MM.
Supposedly all of these figures should convert to 1/72 or HO scale, but they don't. The various sizes makes it hard, at least for me, to mix and match figures from different manufacturers.
Note: Compare the Esci figure with the Strelets figure and you question how the Esci figure can be bigger. Now look at the height of the base of the Esci figure; that is what makes up the difference.
As you can tell I have most of the 1/72 (HO) ACW plastic figures available, but I prefer Musket Miniatures figures because of the variety of figures it offers.
Disclosure: As a sideline in retirement (in between rounds of golf and traveling in the RV), I do paint figures for Musket Miniatures that it offers for sale, however, I do not do it for profit. I paint figures for Musket Miniatures for the enjoyment I get and the creativity it allows me. Also, I think that with its variety and quality of figures and poses, Musket Miniatures has the best 22MM [HO] figures out there.
