Ric Posted February 26, 2021 Report Share Posted February 26, 2021 They both look like Akros to me - weak Corkscrews? Link to comment Share on other sites More sharing options...
Chad G. Posted February 26, 2021 Report Share Posted February 26, 2021 x 2, Agree with Ric, Akro "lazy corks" Any partial rotation like that on an Akro, disqualifies it as a patch and qualifies it as a corkscrew. Corkscrews need not make a full rotation to qualify. Taken from the {MCSA} Marble Collectors Society of America, with permission from and credit to.
