Looks like an M-22 assembled August 31, 1968. One easy way to tell is the input shaft on an M-22 will not have any grooves. One groove would be M-21 and two grooves M-20. This identification method works so long as the input shaft is original to the trans, but pulling side cover is always best.

I've never seen a POP that has the letter of the trans stamped regardless of year or build date of the trans. Oct. 1968 is when the A, B & C were stamped as part of the trans assembly date with "C" meaning M-22 which is why the ebay trans is missing the letter as it was assembled Aug. 31st of 1968. .

If it were assembled anytime during calendar year 1969 it would have an A B or C suffix as stated. Always a good idea to check casting dates on the case and tail housing and make sure they precede the assembly date by weeks, not years.
