If I understand you correctly, I should not shoot 2 3/4" shells in this gun??
I know this gun is in poor shape, would any of you venture on a ballpark value??
yes, correct, 2 3/4" shall not be used.
Regarding value: sorry, out of my range, as the market situation in the US is totally different. In any case: a plus: it's a model XIV, what's one of the better models, as it has catch bars (Sauer's standard model, the model VIII does not). A big minus: the condition.
