I'm back with another unknown junk feed from the Elite Antennas auction.
This was another one of the pieces in the lot they put together from floor scrapings.

The dimensions of the apertures are as follows

1. Scalar end feed opening = 21.9mm. This is identical to a Precision/Elite Ku-Band feed
2. Rectangular window = 17.9mm x 12.6mm
3. Circular aperture recessed into rectangular window = 12.0mm internal diameter

The circular aperture is central in the rectangular window, the angle of the picture is making it look off centre.
There is a smooth narrowing taper from the scalar end to the rectangular window end

I would be grateful if anyone can identify what the feed is for, apart from bin fodder.
Pictures are attached below.

I think it is an old Precision Ku. The knurled ring holds it in a thin ali cup which has the fixing holes for the arms.
