gjmotll - welcome to GMIC! And thanks for reviving this thread - I've been wondering what our friends found out from the various museums. I am not a modeller myself, but you may not actually need to go to West Point for measurements. May I recommend two places that have modelling as primary focus, and at the same time are excellent artillery resources. This site Landships II and this forum Landships WWI Forum as excellent resources for modellers. Some of the most knowledgeable artillery experts known online frequent these sites and I am certain can help you with the modelling aspects. As for the 6th Artillery; this is my regiment and I'd be very interested in your historical artifacts regarding the regiment. As we approach the 100th anniversary of C Battery's historical shot, it would be great to work on an article.
