The University Library Lund in Sweden keeps the most extensive source for horn music from the first half of the 18th century. The music is a handwritten collection of the Academic chapel. Many of the composers therein had somehow connections to the court in Dresden. It is possible that the copier was a hornist who visited Dresden.
This collection Wenster contains 18 concertos for horn - and not 17 how it is always said.

As Reinhardt there is also only a few known about "Sigr Gehra". Probably, it is August (or Johann) Heinrich Gehra. He was chamber musician at the Reussischen court and was organist at the main church in Gera (Thuringia)
