I found a F Dumoulin & Cie Liege 20 gauge yesterday at a local shop. It sports 30” barrels with great bores. This hammer gun seems to have been well cared for and comes in a A&F leather case.
It is tight on face and locks up tight. Wood is in excellent condition. It has pretty plain simple scroll engraving.
I am unfamiliar with the maker and am wondering about what others thoughts are on this maker.
I plan to take another look at it this morning and will take pictures.
