Hal, here's the one I have hanging on the handlebars of my Whizzer: http://www.bikeworldusa.com/product_info.php/cPath/124_25_112/products_id/628
It works well as a toolbag for carrying a few things, but being leatherette it's not really heavy-duty.
Here's a similar one, but in brown (and it looks like it might be leather): http://www.bikeworldusa.com/product_info.php/cPath/124_25_112/products_id/1566
Here's a heavy-duty leather one: http://www.jcwhitney.com/RAIDER-TOOL-ROLL-AND-BAG/GP_2011875_N_111+10211+600014597_10111.jcw
Attached is a photo of the first bag on the handlebars of "Thumper".
I ordered that bikeworldusa bag for my Whizzer.. can't wait to try it out. I've been looking for a classy way to tote some tools and my registration info around.
