I recently obtained this little rifle, knowing that it did not function properly. (it was given to me because of that problem) It was made by High Standard and their model number seems to be 583.70 to.74. After disassembly I find it is missing the ejector, which, from the diagram in Jack First's catalog appears to be mounted in the receiver. I have been unable to locate this part from Numrich and/or Jack First. I have seen a volume of layout drawings of 'obsolete parts', I don't know who published it but is it possible that it could be in that book? Any assistance would be appreciated in locating the part or a drawing. Mike
