Replacement heating element for Heat Treat Furnace

I tring to find a replacement heating element for a heat treat furnace.
The temp is 2300*F 240V 40 Amp Single Phase.
Here is a photo of the setup. There is no manufacturer name on the
furnace but the controller is Barber Colman Controller Model 293C

Take that if you can with you to the /a local furnace/wood stove/pottery supply. They can likely match the fittings(ceramic) and always replace the coil. Tell them what you do - what temps - and that will help them pick the proper metal. Kanthal is the likely best for you.
I've done this with large pottery kilns - measured the troughts to lay the coils in -

If you can characterize the resistance wire (gage and/or ohms per ft) you can buy the wire from mscdirect.com or mcmaster.com and wind the coil yourself cheaply. Porcelain floor tile works well for improvising ceramic heating fixtures, if the old one is not serviceable, and you have no better source.

If you twist the wire together where it burned/broke and put a drop of borax (not Boraxo) on it and light it up, it should weld itself back together. Saw thisin a Popular Mechanics magazine meny, MANY years ago

If Canthal it will do that, if Nichrome - it is brittle by now. Maybe laying it over each other and tying it somewhat tight with wire and then apply the flux.
