I've come across a handful of Tonella boxes. They tend to have steel reeds in them but....you never know. Typically if its a four stopper and tends to have the same dimensions as a standard Cajun box it will have steel reeds, as the steel bronze reeded boxes tend to be smaller. They're not as high of build quality as the Monarchs and Sterlings and fall in the same range as the old Gold Medal Hohners. Another thing to consider is that its going to need a few hundred bucks worth of work even if everything is absolutely pristine condition, just to make it airtight again.
