This new Mr Gasket can appears 100% the same as the NOS earlier can on ebay.

I see a taper on the used can you posted but I think that is the camera or lighting. There also appears to be a ridge around the top which I have never seen a Mr Gasket can have or most likely the top is not put back into place.. What the seller says it is and what it actually is are entirely different.

I remember having NOS Mr Gasket cool can in the old early 70's blue boxes and it was 100% identical to the ones today

The bottom hose tube is longer than the top on the new can and NOS can on ebay

I have sold thousands of pieces NOS speed equipment over the years. Most speed equipment is different from earliest versions but I believe these cans are the 100% same. The difference though may be in hardware. Usually the old hardware was panhead screws and the new stuff is phillips heads and the early nuts usually had separate star washers while new ones are one piece.
