Might have been a mid/late year change for 33. Interesting detail OR maybe a different supplier added detail????. My 33, by engine number was june engine log assembly (4cyl) again, I will have to dig up my original (to the car) radiator and see IF it is on it???The function of the "wedge" is to hold the hood side in open position. It was replaced on the '34s by a notch in the cowl to support the hood on the rear edge instead when open.
Thank you David, added to memory banks!!Robert,
The "wedge" cited in #4 is only on late '33 radiators.
