Gorgeous Dave, thanks for the photos. Mine is very similar indeed, to both in fact, but has a lip plate. So, here is a not so very clear photo (more photos coming soon):

“Fentum 78 Strand London”, ca 1840.
The tuning is particularly good, lovely intonation. Sterling silver and I haven’t quite figured out what kind of wood it is: it’s much darker than cocus, looks very like blackwood with yellow flecks appearing under bright light.
The following ad (from The Lancet, 1844) seems to talk about this kind of flute (with “tips”, caps on each end, which Dave’s flutes have too, and which may be considered the “patent head”?) and so 1844 sounds right with Henry Fentum as maker:
Flutes, 78, Strand – Eight keyed Cocoa Flutes, with patent head, silver keys (double springs), tips, & c., with rosewood case, cleaner, and instruction book, 5l. 5s., or German Silver, including case, & c., 2l. 12s. 6d., manufactured by HENRY FENTUM, Professor of the Flute, 78, Strand, London. Flutes repaired and taken in exchange.
It looks very like Francis Fentum’s design too, so did they work together, or run around to each other’s workshops to copy designs? The keys looks like the work of Wylde.
