Rare 1850's English wet plate collodion sliding box camera, quarter plate

Description

For auction is a very rare 1850's English 5"x5" wet plate sliding box camera in fantastic unrestored unmolested condition that belongs in your antique camera collection or a museum.  Given that this camera was made approximately 160-years ago -- during the early days of tintype photography -- it is in remarkable working condition.
The only identifier on the camera is inscribed on the lens barrel: "E. Mander, 98 Snow Hill, Birmingham." This camera was likely sold by an early UK photography figure Elisha Mander, who had a photography shop and imported Colas lens in the 1850s, according to the website Earlyphotography.co.uk:  http://www.earlyphotography.co.uk/site/companies2.html. I haven't been able to confirm when Mander started selling cameras, but have found several advertisements he ran in photography journals starting in 1857.
On Larry Pierce's camera website Piercevauble.com, there is a profile of an English box camera, estimated to have been made in 1850, almost identical to my camera: http://www.piercevaubel.com/cam/nonview/slidingbox.htm
Here's another similar looking camera with a Colas lens: http://www.earlyphotography.co.uk/site/entry_C700.html
And one more very similar looking camera, described as a "Colas Daguerreotype Camera" dated 1845, was sold on the Liveauctioneers.com website: https://www.liveauctioneers.com/en-gb/item/4348006_1669-b38-colas-daguerreotype-camera
The dimensions of my camera are as follows:
- base: 7" width x 10.25" long
- box face: 7" width x 6.75" height
- box length closed:  5"
- box length extended:  7.75"
- ground glass:  3.25"  width x 4.25" height
This camera is made from mahogany with a beautiful French polish finish that has appropriate silver nitrate stains on the camera body and dark slide and scratches from many years of use. The craftsmanship is of the highest level with exquisite hand-cut dovetails on the camera body, thin wood splines and perfectly inset brass hinges on the dark slide. The front of the camera is secured with several brass screws and there is a tripod mount on the bottom.  Please note a slight but noticeable crack in the back of the camera around the slot for ground-glass holder.  You definitely need to be gentle when removing and inserting the holder and dark slide.
This camera comes with a superbly-made dark slide, which has a  wood insert with wire corners to hold tintype plates.
As noted above, Elisha Manders sold Colas lenses so it is possible that this lens was private-labeled made by the French optics firm -- see this nice background on Colas: http://www.earlyphotography.co.uk/site/entry_C700.html. The lens is in original condition and does have the typical issues for very old ones:  dust, some fungus and hazing around the edges.  The camera came with a crude paper stop for the lens that you install by unscrewing the hood of the lens, which is focused by sliding the box back and forth.  The lens has a burgundy-colored leather cap that is in good condition with some wear on the edges.
This is a working camera that I used about 10 years ago for tintypes and calotypes. Detail in the tintypes was surprising sharp, but unfortunately I don't have any examples of them.
Please let me know if you know if you have any questions about the camera which I have endeavored to describe as accurately as possible.
