the wavey is a texture overlay in Photoshop. took me months to find/edit/build a good looking one. I've heard vector software is better for it, but I could not figure out how do it on my own, and no one I asked would help.
Standards are always a problem. sometimes standards received were not used until the old ones were captured or wore out. so either of us could be right in these circumstances. it gets even worse when you consider that there are at least 3 different types of flags, and each have several sub variants, that can be issued for honours and such. so we might know when the flags were issues but we don't really know what anyone was actually carrying at any given time.
My research has revealed(from at least 2 sources) that the Orel regiment(and a few other from other divisions in other corps) were newly raised(less than 6 months prior) regiments from depot battalions of other units. when they took the field at Borodino, they supposedly still had the standards they had as the 3rd battalion of whatever regiment they came from(new ones had not yet been issued). which means the battalions likely had different flags. so it's quite possible that we are both correct. I just used the one shown in the hourtouille book(terribly pro-french, but the platesare beautiful and they seem to closely match with my own research)
I don't have the osprey to which you reference. so I have no clue what your poltava flags looks like. I'm not sure what the quality will be though(I'm not much of a powerpoint user for anything other then what i have to)
also, you can save powerpoint files as several image formats by going to save as and using the drop down menu.
and my flag files are generally larger then i need, so that when i print i can resize to my hears content without compromising detail(although I'm sure at something like 1/6th scale they would start to be rather crappy
)
for the record, if anyone wants a flag that is the same style as one of mine, but different colours, let me know. i keep templates of everything with separated layers so i can changes the colours and produce a new Jpeg in a minute or 2. PM me.
I've been on the receiving end of a big "no" before when asking for help in developing the resources, so I try to set a better example (as long as it's not going to take a significant amount of time of course).
