Help with Mariette Pepperbox

[Shooting Centre]

We just received a very nice Mariette pepperbox in on consignment. BUT it has 8.5" barrels something we have never seen before. Can anyone point us in the right direction as to scarcity/price. Condition is exceptional, no rust or pits. On screw head was scarfed up at some point but everything else is perfect.

How many barrels has it got???Some of them had 18 barrels (Rare),a search on the Internet should get you a ballpark figure for your particular model.
Would like to see some pictures if possible.

icollector.com Item 375b looks pretty close. Starting bid $175. Undisclosed sale amount. Valued $300-700
Hard to find with longer barrels. What do they measure?
