Hot Rods Silvertown Blackwalls

I found a set of Silvertown/B.F. Goodrich, 8.00-15, 4 ply bias tires. I know they still make the whitewalls and red stripe, but have yet found a blackwall bias Silvertown tire in that size available today. The tires look new but are probably older than I think. Anyone out there know anything about the age of these tires or when they quit making them? I plan to run at least 2 of them on my ride. Any comments would be appreciated.

I wonder if Coker made those.......
