Very kind from all you providing those ideas and examples
@Basilhare, I think the 3" sabots could be misinterpreted if/when charged in close combat by a single-base column if they are "caught" in compres...but thats probably so bizarre as to be left out of account
@drferling , yours seems the same solution as basilhare´s , I specially appreciate the spanish photos as I mount infantry in three figures/base myself (not cost but painting time being the constraint for infantry) .it allows me to see final effect
@TodCreasey that seems another good idea, even convined with the previous ones, adding flexibility at low cost. As a side question, I ´ve read Old Glory guns are a little downsize related to their own artillery crews, is that true?
Thanks again to all of you, I promise showing the final results!
