Vintage Brass Large Format Photography Lenses c/w Flange in Guelph, Ontario for sale

I recently got two vintage brass photography lenses to experiment with, but not suitable with the 8x10 I have.

The first is a Lancaster & Son Landscape style with a FL of around 5" (12cm). It looks to illuminate about a 6" (15cm) circle. It includes its flange mounted onto a wood lensboard. The lens has a built-in iris. For more information on Lancaster & Son and their Landscape lenses, see: http://www.earlyphotography.co.uk/site/entry_L6.html
Price is $175

The second lens has no name. It has a FL of around 6" (15cm) and illuminates about 7". It has a slot for a waterhouse stop, but none are included. It does have a flange. There is some separation in the front set of elements and it priced accordingly at $100

Please feel free to ask any questions.

I will revise the listing as needed and delete it once the lenses are no longer available.
