I've no ready-made designs to suggest, but a good starting point might be a circuit shown in AN45 figure 29 in the 1993 Linear Applications Handbook from Linear Technology. This circuit boosts the input voltage (4 to 20V) to 90V, but should be adaptable to 130V appropriate feedback resistor values. The VCE max of the 2N5551 in the circuit is 160V - you might want to find a higher voltage device for increased margin.
Hope this helps.
