I don't know how, but Darwen Brass have lost two different parts for two different pieces, They are-- 2nd Baritone part for "Trailblaze" by Goff Richards. 2nd Trombone part for First Suite in E flat by Gustav Holst arranged by Sydney Herbert. The first one may be reasonably easy to get, but due to its age the second one may be impossible as it is an original Boosey & Co from 1921. If any one has access to, or can provide copies of the above, we would be grateful. any costs will of course be reimbursed. Please PM me if you can help.
