Vintage LRP Le 25 ams esc - what's it worth?

[I-B-Quick]

Hi

I have from my much younger racing days an LRP 25 AMS coupled up to a Reedy Sonic Motor.

The speedo is fully working with the original instruction sheet plus all the little coloured restrictor chips and the rubber blanking plugs.

Are these collectable and can anyone put a value on the items for me as I have no use for them so they can help fund my modern gear I hope.

The speedo is as per the image here:
