B S 23 FBC Oil level

I have a 1951 23FBC and I'm not sure where the oil level should be.
It has the extension tube and spring held cap. See attached photo.

According to my old Chilton's Repair & Tune-Up Guide For Small Engines, it says B & S Cast Iron Block 23, 24, 30, 32 Cu. In. Horiz. Crank engines take 4 pints of oil. It also says to " Fill the crankcase to the top of the filler pipe when their is no dipstick. " It seems like 4 pints is a lot of oil, but if it takes that amount and is level with the top of the fill pipe, then the book would be right.

Ok that makes sense based on my refill amount.
Thanks to both replies.
