Currently, there is a bid auction for a BBC Coded Music LP (Specifically CM198, featuring the Gert Wilden Group and the Dresden Dance Symphony, cond. by Günter Hörig) on eBay right now. The BBC Coded Music Library was a library made for internal usage for the BBC, and had LPs (Usually other library LPs with BBC stickers on them, and some occasions original LPs with other unique recordings as well) were used for the BBC test cards. There isn't a label page for this label, but apmnut did talk about this label in a request post here:
