I couldn't resist this tiny lens and its delightfully simple matching rotary shutter. The shutter has a joined M and B logo, which I'm pretty sure is Marlow Brothers of Birmingham, UK. They only traded as Marlow Brothers for a short period and if this is correct then it dates from between 1893 and 1904.
The shutter is in need of some attention - it works if wound to the farthest notch but sticks on the other two. It obviously need plenty of 'oomph' to travel the entire distance. The narrowest bit of the aluminium has a kink in it (which will need some gentle 'adjustment'), and this can't be helping.
My question is - what is the purpose of the two black pieces that are mounted on the silver aluminium disk? The larger of them is itself made up of two pieces.
The shutter has some similarities to the one on this camera on the Early Photography website (http://www.earlyphotography.co.uk/site/entry_C839.html).
The lens appears to be a simple meniscus and has three rotating stops - any guesses as to what plate size this would have been for?

Many thanks for any info.
