These two figures were included in the mixed lot of Garrision Romans which I picked up from eBay recently. They are substantially larger and heavier than the others, which makes me assume they come from the 25mm range. Click on the image for a larger version.
The foot figure has "Garrison" printed on the bottom of his base, and covered in resin or varnish of some kind.
As with the smaller models, I cannot find a catalogue number and description on the current website for Garrison that matches these figures precisely. If you do know the code for either of these miniatures, please reply to this post.
