New score-Movie accurate coveralls???

Picked up these blue JC Penny big macs for $50 off of ebay.
Now I’m not really an expert on the brands or accuracy of these compared to the movie coveralls but they look pretty damn accurate to me.
Am I correct in thinking it was charcoal blue big macs for H1 and reeds spruce green for H2? How accurate are these as I heard seams were slightly different at the back of these big macs?
Would appreciate some opinions on these and regardless of whether they are 100% accurate or not…they were only $50 so pretty happy with the purchase.

Those are pretty close, i have the same ones i think! they were actually olive wood colored Big Macs, with NO seam down the back. H2 were Sears work/leisure spruce green.

Thank you for the info its much appreciated. Don’t know where I came up with Reeds then :laughing:
