Have a look on this website which (may take a bit to find the right map/scale) should show historical boundaries and compare with the legal version from Land Registry. Last time I used Land Registry online it cost £3 for a copy (pdf) of property and boundaries.

That said, scale of the map might mean that your dispute is over the thickness of the line drawn on a map. Didnt work well for a boundary between Israel and Egypt.
Looking at our property boundary, next door appear to have pinched about a foot to build an extension that cuts into our diagonal boundary line. As that extension was built over 30 years ago, before we moved in, nothing we can do about it now. Not that we want to.

Good luck with your neighbour.
