I'm pretty stoked on this ebay find. I was looking for a cheap vintage Sparto Made In England tail light for the '55 Trump when I came upon a "Harley Sparto" tail light for $50 buy it now. I looked at the pictures and it looked more like the older Barnett Tools and Engineering bobber tail light from the 40's/50/60's out of Ventura. Sure enough, there was a picture that showed the BT&E stamp inside the housing. I snagged it up as fast as I could. The last one one ebay went for $225 with a cracked lens and beat up housing. They often sell at $400! This is the same one that is on the '50 BSA B33.
