4 Vintage Alva Skateboard Wheels, '70s

Description

These 4 vintage Alva skateboard wheels are original '70s wheels.  They are not reissues.  They are green in color and almost 60mm diameter and 48mm wide.  They have some wear as expected for used skateboard wheels.
The vintage bearings are included.  They still roll fine but I can't tell what brand the bearings are because of the accumulated dirt.  I can make out the word German on one of the bearings.  I'll try to update the brand later.
Only the 4 wheels (with bearings) are for sale.  I may sell the trucks or deck at a later date.
This board has been in my closet for over 20 years.  I collected vintage skateboards from 1990-2000.  I thought I'd sold them all in the '00s and so I was surprised to see this lonely guy in there with my other "valuables".  So this is my first step to part it out.
I'm located at 92683 if you want to pick it up locally.

I took the wheels off and flipped the bearings to their cleaner side.  The bearings are marked AZF Speed German.
REMINDER: This auction is for 4 wheels and bearings only.  No skateboard and no trucks.
