Instrument makers Kemp & Co. from Edinburgh - any info?

[Ron (Netherlands)]

Just acquired a nice camera made or traded presumably by Kemp & Co from Edinburg. It seems to me that my camera very strongly resembles a type of camera made by Butcher & Sons, like this one (not my camera, just a picture from the internet):

On the net I found the below messages/advertisements regarding Kemp & Co. that stem from the Scottish post office directories, but no further info on the photographic equipment they sold/traded. Does anyone have any additional info, like catalogues and the like?

from the 1869-1870 directory:

already mentioned in the 1850-1851 directory:

It seems that currently the University of Edinburgh is settled on Kemp & Co's former premises.

I didn’t know about Kemp & Co. But they Seem to have been quite succesful - almost parallel with the other scottish Company, Lizars. But they specialised as suppliers to hospitals, rather than the new hobby of photography.

Thanks Steven, indeed they seems to have chosen a different kind of (major) trade....
and I'm quite confident my camera must be a rebadged British made camera by Butcher since it is very much alike The National.
