Here is the link to the cross section of the polished spinner I posted the pics of earlier. This is the one Sensenich markets to go with the 69CK prop in the Ebay ad to be used on '59 150s up thru the '70 150K.

Here is the link to the cross section of the spinner Sensenich markets to be installed with the S69CK prop and spacer to be used on the 150L and 150M models. Note that this is the EXACT same spinner, and component parts that are used on the 152 Sensenich prop installation and the Sparrowhawk 152 prop installation also.

The Ebay advertiser is advertising a mix match of parts, a new 69CK prop for 150's up thru the 150K (old type cowl) and a spinner for the S69CK prop for the 150L and M (new type cowl).
His loss is someones gain.
