m1634 ceramic stoneware bangle (badge)

 Read from r. to l.: 

Vikalpa: The prefixSign 403: Hieroglyph: bārī , 'small ear-ring': H. bālā m. ʻbraceletʼ (→ S. ḇālo m. ʻbracelet worn by Hindusʼ), bālī, bārī f. ʻsmall ear -- ringʼ, OMārw. bālī f.; G. vāḷɔ m. ʻ wire ʼ, pl. ʻ ear ornament made of gold wire ʼ; M. vāḷā m. ʻ ring ʼ, vāḷī f. ʻ nose -- ring ʼ.(CDIAL 11573) Rebus: bārī 'merchant' vāḍhī, bari, barea 'merchant' bārakaśa 'seafaring vessel'. If the duplication of the 'bangle' on Sign 403 signifies a plural, the reading could be: karã̄ n. pl. wristlets, bangles Rebus: khār 'blacksmith, iron worker'.

The pair of signs on 1634 ceramic stoneware bangle confirms the reading of Sign 51 as khār'blacksmith' śrēṣṭhin 'guild-master'. Sign 403 on this bangle is thus a semantic

 determinative of the professional competence of the 'squirrel' hieroglyph which signifies a 'guild-master', specifying him as a 

guild-master of blacksmiths, artisans.
