Vintage 620 game accessories

[Shabby J]

Fellas, I do not remember in great detail the accessores that came with the many 620s I had as a kid, but I have a question. I have bought two vintage620s on Ebay and one at a garage sale and they all had the usual accessories, all three sets had the yellow modern style goal posts and also on the separate sprues in all three sets are a pair of white
H-type old school goal posts, however, on all three fields there is only one whole in each end zone for the modern yellow goal post.

I have seen pics on ebay and other areas of the Internet and I see a lot of older 620s with both style goal posts, what's up with this? I am 40 years old and do not remember this in the many new board sets I had as a kid. Am I missing something here, anyone know the reason for this?
