Late to the party as always, but yeah, you've got a normal Worksman industrial front hub.
I thought something was wrong too the first time I took apart my work bike to replace a tube. Then I realized the axle came out... then I read about it on their web site... then I understood!
They are heavy beasts and tough as nails. If anything, the Shimano coaster hubs are probably the weakest link, but I've carried all kinds of heavy stuff, ridden mine hard, skidded it, gone through 6" deep floods of um... mixed materials... in the paper mill I work in. It always puts up with the abuse and keeps working.
I did come back from a vacation and find a broken coaster-brake strap though... so I suspect other people have been less nice to it than me. And I have had to grind away a bit on the rear dropouts to get the axle in and out. Mine has damage from over tightening the rear axle nuts, before I got it.
Still a great tool that helps me get more done at work.
