The extractor springs are the same for all variations of the Rifle No. 4.
Try www.gunpartscorp.com for the spring; their part number is 486800; cost is about $6. For many years, gunsmiths have been modifying those extractors to take a coil spring, but of course the cost of the modification has to be balanced against the cost of one or more regular springs.
