I bought these on Ebay to try them out on my 1912 Flanders, but  haven't used them.  They are designed to strap onto bicycle tubing, but I made some magnetic mounts with wood dowels for them to strap onto.  Here is a link to a short video showing how they work on my Flanders:

Price for the set is $25.00 including shipping via a USPS Priority medium flat rate box.
If interested, PM me with your name and address and I will reply with payment instructions.  Thanks!
