The felt looks to be 'wrong' to me.
As far as lozenges are concerned, they often came off and these early Jaques rarely had more than a few left. There was a well known chess dealer in Portobello road who kept a saucer of lozenges in his shop to add a few to any likely sets which came through his hands. He at least didn't put Indian knights heads on early ivory Jaques sets and then make up a faux classification system to justify it.
Felts look original to me.
