A recently purchased Diana 75 T01 had its front sight damaged in shipment, so I am in the market for a replacement.

I have the later variant of the Diana 75, which uses a somewhat narrow dovetail, measuring 8.77mm at the widest part. (The dovetail on the sight itself is roughly 10mm at the widest part.) There were two versions of this sight on the later 75, and the one I am looking for is the shorter one, which measures roughly 18mm from the top of the dovetail on the gun to the centerline of the sight. The diameter of the sight tunnel is 18mm as well. There is a taller variant, which measures roughly 28mm from the top of the dovetail on the barrel to the centerline of the sight. Mine is the shorter of these.

Many thanks for anyone who can provide one or a lead on one.
