Since Charles Eastlake never made a single piece of furniture,, the cabinetmakers/mfrs were free to use what they wished !! He just published a design book !! Thats it !! So when he said to simplify,, they took broad rein !! Usually they continued to use whatever they had in stock !! Thats the reason you can`t always date furniture by hardware !! I look at the piece itself and how its made, then take all the little things into account !!
Just thought about it, but if this person is in the UK,, it could certainly be as early as Ghopper said !! They ( some styles) usually didn`t make it here (U.S.) till a bit later !!
And in the UK it may be considered more Eastlake style than what we see here !!
