Hi again John,
Here, as promised is an image of the 92nd Highlanders pattern sphinx badge :
Admittedly, this is a bonnet badge in white-metal, but is I believe the same design (in brass) as shown both in the P.P.Holder article and in Churchill's book as Fig 1699. Incidentally, the illustrations in both are unfortunately very poor, tho' there is another example shown in "Bloomer" which is marginally better. I can only assume that both Churchill and Holder have seen the smaller collar badges of this type in brass. Regards Jeff
