Thanks for the suggestions. The issue was indeed the locks not being cocked and using a variation of the SKB idea solved the problem. I found the forend could slot enough into the cocking lugs with the gun broken apart slightly and with just a bit downward applied to eh forend was enough to cock the locks and this was the result. All good. Now to make another mental note to not dissemble with un-cooked locks, and how to reassemble in the case of forgetfulness how to reassemble and add the Churchill it to list of actions that aren't real friendly if broken down unlocked...
