Never once seen that part being sold separately from the deck. Here, the U.S., etc. No harm in sending out enquiries but suspect the 3D print option will be the best route to explore. Looks like a French firm does them for approx. €25.

Still not sure how it came to be missing, previous owner may have been trying to get the roof fixed and they forgot to put the part back on... Will probably have to go down the 3D print route, there is another £20 carriage on that price. Be good to get an original. Thanks M
