I have a model 18 crutchtip and can't find much information on the early models. I have seen some that come with a Johnson sheath, but mine came with a Randall sheath. It has the proper markings on the crutchtip and I have had it since 1974 so I know it is the sheath that came with it. If anyone has any information or can direct me to it I would greatly appreciate it.
Thanks
