YH Wheels - these look fake stamps?

[rszmjt]

Not ALL YH wheels have the dashes between the K 1 9. I have earlier and later original YH wheels that do not have dashes, BUT all my Feb. 27/27/27/26/27/ wheels have the dashes.
These wheels also look like they have the small slots, like later YH or FW wheels. ALL pre Sept/69 YH wheels have the bigger irregular shaped slots.
TXZS is correct, all my wheels are stamped from the outside.
I was hesitant to post this info because of forgerys, but seeing as it has been discussed here as well as on another site, i thought i would ad my .25 worth.
I took pictures of my dates, and if some one can post the pictures i will email them to you.
Hope this helps.
