#7 Modules for the Elite Echelon or Revol XL

These modules fit the Elite Echelon 37 and 39, and the Revol XL, and are the #7 module which equates to 28" draw on the Echelon 37, 29" on the Echelon 39, and 29" on the Revol XL.

They are as new and have never been fitted.

Ideally I would like to swap them for the #6 module in the same condition.
