The shape of the 'elbow' in the innermost cross-line suggests Treble-bar, being rounded and not forming an acute angle, unlike the Lesser treble-bar which usually has a sharper, acutely angled elbow in this line. The ID is probably correct therefore but to clinch it it would be desirable to have an underside view of the tip of the abdomen.
Thank you, Jonathan - will know what to check next time.
