1971 Topps Variations: 2nd Series Checklist #123

Now we get into the confusing part of the 1971 Topps variations, the checklists. From what I can find the series 2 checklist comes in three varieties.We will call them 123A, 123B and 123C.

123A - Has the number on the back of the card centered, and the helmet on the front of the card has the black accents.
123B - Has the number on the back of the card in the bottom right, and has an orange helmet on the front. 
123C - Has the number on the back of the card in the bottom right, and has an red helmet on the front.

I am finding it very hard to tell what is an orange helmet and what is a red from scans. As far as I can tell the black accents only appear on 123A. What makes things worse in that I have seen "number centered" cards with a orange helmet notation.

The O-Pee-Chee versions have the same number placement variation, but I can not find anything on the helmet colours for OPC. The OPC checklist also differs in card #161, Topps has the coin checklist, while the OPC has Ron Hunt. This is because coins were not found in OPC packs. The back of the Topps also lists card 202 as "Reds Celebrate" and the OPC set has Claude Raymond. Topps added some extra Expos in the OPC set to add Canadian interest.
