In 2023, the Regional Museum in Louny provided access to a homogeneous collection of four prayer books from the years 1800–1837. The oldest of them (shelf mark S 6460) is written German, the others in Czech. Two of them (shelf marks S 6229 and S 6458) were written by Václav Bulánek, a teacher in Kralovice, who also copied a similar manuscript, which is now deposited in the Prácheň Museum in Písek under the shelf mark L 157 950. All of these codices are decorated with simple hand-coloured pen-and-ink drawings.
