Kirk Photo BL-D3 L-plate, Arca-Swiss compatible - Near Mint condition with no issues.  Had a few of these for my D3 cameras which I've sold.  This is the last one I have for sale.  Hard to find in the this condition and price.  Selling all my Nikon gear due to health reasons.    Check my feedback and buy with confidence.  No returns please.  Ask questions prior to purchase.
