Wish I'd seen this earlier this year when I wired my 49. I couldn't find any such thing and ended up making my own lamp terminals from pop rivet heads (to avoid splices), but it was time consuming - found I had to turn down the diameters on my lathe to get them to sit in the socket right and just generally a lot of messing around. I'll have to buy some of these now for the next upcoming re-wire.
