We use two methods, Andrea's Brompton has a bag bracket welded on the front of the headstock, we took the frame from the bag and cable tied a traditional bike basket to it, this works very well and Mia (the dog) is convinced that the Brompton is "her" bicycle. This probably depends on having the bracket welded onto the frame.
I have another basket which is actually for sale, I've only used it 3 times, it works OK but we trained Mia on the other so that is the one she IDs with. The basket attaches to my hack/load carrying bike which is a streetified mountain bike. This has a chunky alluminium bracket that clamps to the headstock, the basket has two rails extending backwards from the base and these slot into the clamp. This means that the basket extends forward from the bars, and is only slightly lower. This basket may well be the right size for a springer. I can post photos if you like?
