I do not have a 54mm (1/32 scale) Lutheran Seminary building for Gettysburg, nor do I wish to have one as it would be a HUGE model. So instead I used an observation tower made by Herb Gundt and placed an officer with binoculars up in the tower. The picture of the tower, previously posted on my blog, had a Union officer in a pointing pose. 

I found the officer with binoculars in the Armies In Plastic Union Artillery set of figures. The figures are all wearing long frock coats so I cannot use them. However, the officer figure can be used in my project. I have an idea to convert a mounted officer figure by swapping upper torsos and making a Union officer sitting on his horse and looking through his binoculars.
