A reputable valuation requires precise model identification on the basis of detail photos as well as a condition assessment; general blanket statements are not to be expected from a collector forum, since the forum does not replace a professional valuation. Anyone who has no relation to older writing instruments and wishes to sell the piece reaches the broadest collector circle through eBay and thus a market-near price; the listing should contain a detailed description with clear pictures. A dealer offer of 160 euros lies in the lower range for a 1920s push-filler but, depending on model, condition and nib quality, can be appropriate or clearly below.
