US experimental Cal. .90 inch cannon

I've put together an article on the US experimental T1-T4 series .90 inch cannon and posted it on my website here: http://www.quarry.nildram.co.uk/CAL90.html

 

More interesting stuff per your usual standard. Thank you Tony.

 

Tony,

Very interesting.
It Looks like a grown up .50 Cal Browning.
One Thing for sure, it would not be healthy Standing in the line of fire.
