  1. Hello, i have been trying to reconcile some of the apparently conflicting identifications of confederate rifled artillery used around Vicksburg . One reference has stumped me- reported at Ft. Pemberton a ‘Whitworth 3″ rifle firing an 18 pdr bolt. I have not been able to find any hard information about such a weapon. I am wondering if the respondent is merging in his mind the 2.75″ Whitworth rifle and the 18 pdr converted siege rifle. Both these pieces seem to show up everywhere during this campaign, often together. Any ideas? Thanks.

  2. These articles are very helpful to my team refurbishing an excellent undamaged Ordnance Rifle (late series 7xx) that still is on a sound wooden carriage. We have figured out the painting process: white lead/linseed oil was applied to the freshly polished tube and then was coated with the usual prescribed black paint. Beware of the dangers of lead paint.

    Also, we have determined that the carriage was painted a brownish yellow. There is not evidence of OD anywhere on the carriage.

    We are developing an HD documentary of the entire process.

    Thanks for all the good work.
