At his marriage on 15 August 1741, he was described in the register as 'Jakob Felchis, porcelain painter, widower, born in Triest, resident in the porcelain manufactory' (C. Lehner-Jobst, History of the First Vienna Porcelain Manufactory, in Chilton/Lehner-Jobst, vol. 1, p. 212). He was subsequently in Munich, where - between 1747 and 1750 - he was involved in the early attempts to produce porcelain at the nascent Neudeck (later Nymphenburg) manufactory (F.H. Hofmann, Geschichte der Porzellanmanufaktur Nymphenburg, II (1922), p. 337).The closely similar silver-mounted ecuelle and cover, also signed on the cover by Jacob Helchis but lacking a stand, is in the British Museum (Sir A.W. Franks Collection, inv. no. 163; published by Chilton/Lehner-Jobst, no. 329). Both the Franks example and the present lot were in the collections of C.W. Reynolds (mostly sold at Christie's in 1871, the remainder in 1874) and, subsequently, James Sanders.This lot is subject to the following lot symbols: ** VAT on imported items at a preferential rate of 5% on Hammer Price and the prevailing rate on Buyer's Premium.For further information on this lot please visit Bonhams.com
