Wow - Hammond decided to bring enclosures and transformers to NAMM - they brought tons of 1590G for free samples (so I got 15), but on the last day they gave away all of their samples for free. Here is my haul...
The yellow 1590bb is small than the 1590XX in red/white and blue ones, then there are three octagonal (orange purple white), two trapezoids (big yellow, small purple); two purple 1590BBL an a small 1590bb (yellow)
