I have one of Jeff's leather and wood cases, the last one he had for a Browning BSS. Fits perfectly. Very nice quality. I also have a couple of the Guardian cases I ordered from England and they too are nice and of equal quality. Last but not least, I have a Tourbon case made in China and they are quite nice for the price. I have no idea what hard material is under the leather of any of these, but they all fit and feel the same. Between Tourbon and Guardian, I like the Guardian better due to better quality straps on it. Otherwise, for around $200 +/-, they are all pretty equal.
