Thanks, unfortunately there's no patent date or number. I've searched online everyway I can think of and no luck. Between the pair I have and the other style which has the info on the lower wider part of the handles, clearly mine were manu. first. I'm just wanting to find a date and maybe pics...
All the other pairs of these have had the info on the handle area with info about replacement grippers. Can't find any info on these differently marked pairs. Thanks
Thanks I appreciate your welcoming me to the site. To answer your question, no other markings, except exactly the same on the other side upsidedown. I'll put up a couple more pics and you'll get a better view. Newbie mistake, my apologies.
