It's a Worksman industrial bike I'm not sure how old. I'm gonna see if Worksman can tell me (from the serial #) the year and maybe even who they sold it to. Boeing used to use a lot of these for personel transport.
The spokes are 3 cross, some were no longer attached to the rim (explains odd crossing) but these went under under under and over over over. After speeking again to the previous owner about what happened to them (after all when 2 worksman wheels are destroyed you have to know) it turns out his hog got out and layed up against it

No really! But I saw no evidince of relacing that's what's perplexing. I completely disassembled both wheels and had enough straight ones to lace an mb freewheel hub onto a steel rim I got off another of the five bikes in the lot. And the front doesn't need to be heavy duty so I left it's match intact and I'll mount u brakes front and rear for now. I'm going through it and making everything work right but I still want it to look old or else I would have built new wheels for it. (I may eventually anyway). Part of it too is the challenge of spending as little as possible to make a real heavy duty mb.
The frame has a zerk on the bottom bracket, I think the bottom half of the frame is full of grease!
I'm fitting a 4 stroke into it and it's tight so I'm making a custom engine mount out of 3/8" Aluminum plate. I'll post some pics tomorrow. The bike is completely disassembled and I'm just getting the motor prefitted then removed before I prep the frame for paint; I don't have to worry about scratches that way and it'll go together like legos after paint.
Oh yeah the rear brake works I'm sure but the bearings need lube. I'll tell ya though if I even considered using the "rubber donut sprocket" that would be the hub, it's beefy!
