Draw Bar length on B1 Kit on Grafar Chassis

[allot-ment-spel]

Hello, I have recently bought a B1 4-6-0 kit-made on a Grafar chassis (Black 5 I think) The kit tender is riding too close to the loco which derails on anything but wide curves. Does anyone know if a slightly longer draw bar is available to give a bit of extra space between loco and tender, which would probably solve the problem?
Many Thanks

I have a Langley white metal LNER B1 kit on a GF Black 5 chassis.  I am not sure if my draw bar came with the loco or I made it at some point.  I have obviously painted it.

The dimensions are:

     Overall length = 14mm
     Hole centre-to-centre = 11mm
     Width = 4mm

My B1 has no trouble going around Peco radius 2 curves (10-3/8 inch radius).

Various draw bars are available from Farish 'N' Spares: https://www.farishnspares.co.uk/

But it may be just as easy to fabricate one from brass or plastic card.

Hi Ian, Thank you for the great detail in your reply to my post. The original draw bar is 9mm centre to centre. I contacted nfarishspares/LP Rails and spoke to Lee Palmer.  He drilled me an 11mm (c to c} and that extra 2mm makes all the difference. The loco negotiates everything beautifully now. I cannot recommend Lee highly enough. Thank you again for your detailed reply.
