DOC, here's some police work for you. no sled is guilty till proven so. the felon: RUSS A. PRITCHARD, noted CIVIL WAR EXPERT and FBI most wanted. the first book i posted was all PRITCHARD, he lists the mortar as CONFEDERATE, that book is 2003.........the second book i posted by WILLIAM C. DAVIS is second printing1999,but PRITCHARD was TECHNICAL ADVISOR, he is the expert in all things civil war. do a google on PRITCHARD,he has been nabbed countless times for cheating people. he tells them their CIVIL WAR items are fake, buys them cheap, resales them for a big fortune. the FBI see's him often, something to think about anyway............... i got a cool original story about CONFEDERATE MORTARS in use, i'll see about linking it to here, maybe i can find it and post it later. OH, one more thing, how about you and the guy's in the crime lab going over this picture. the pic is captured CONFEDERATE ARTILLERY, most folks look at the close up of the CANNON. but, in front of the barn door, i see what i think is TWO MORTARS with DIFFERENT BEDS. one BLOCK and one FRAME SLED, looks like the short frame bed like i posted. 4th pic page one,GREEN SLED. if so, that would be an original pic of the GETTYSBURG SLED..........
