A rare Weaver zither banjo

Douglas Rogers has sent us these photographs of his Weaver zither banjo recently restored by Dave Stacey:

This is fairly rare instrument: a Weaver zither-banjo, of perhaps pre-Great War vintage - the machines certainly look Victorian.
I bought it some months ago. It needed a new vellum, its tailpiece straightened (!) and the veneer on the front of the hoop rebuilt. Dave Stacey has done his customary beautiful job on it. As always seems to be the case with Weavers (for whatever reason), the neck/fingerboard was in superb condition, without twist or warp.
 

The neck and peg-head is mahogany, the front veneers all ebony, and the hoop is oak with rosewood veneer.
Its overall length is 92cm. It has a 67cm scale length, with a 21.4cm vellum and 27.5cm hoop whose domed depth is 6.5 - 8cm.
Its fingerboard is quite wide: 3.6cm at the nut and 4.7cm at 12th fret. I find this very disentangling! 
Comparing it with my Vibrante Royal - a much larger instrument (5cm longer overall),  the nut width is the same and the 12th fret 1 mm less.
Alfred Weaver (1857-1939), was arguably the foremost English banjo maker.  All I know of him I have gleaned from 2 sketches: Richard Ineson's at The Unique Joe Morley website, and A.P.Sharpe's in BMG of November 1973. The latter source has one sentence that is of particular interest for my own little commentary: "He made some zither-banjos at the height of the popularity of the instrument, but they were inclined to be heavy and lacking in true zither-banjo tone." 

Who knows which of how many Weavers Z-Bs APS had tried - if any. It's not impossible he was passing on someone else's opinion.
My instrument is certainly sturdy, plain, restrained, its elegant lines and curves un-distracted by decoration - it has a different 'look' from other Z-Bs.  At just over 3 kilos it is very slightly heavier than a Clifford Essex Z-B #1 I have, but 1.5 kilos less than the Royal! 
As for "true zither-banjo tone".. well - its 'generic' tone is pretty much the same as all the other zither-banjos I have played.
Nevertheless it seems very even in its response and sustain, has plenty of volume, a particularly rich sound, and is easy and very comfortable to play. It should not be forgotten that all this is subject to hefty doses of subjectivity; differing vellums (and their tension); strings (I am using the usual metal 1, 2 & 5, with nylon 3 and ditto wound 4); varieties of bridges; the action - not to mention player-related matters! 
I wonder if anyone knows of another Weaver Z-B... Perhaps they were all massive, unwieldy tone-freaks - except for one, of course...
