In the text of Small Santiago we discovered that this character (GD53) was represented by two different types of glyphs. The same seems to be the case in Large Washington:
 
Sa1-207 Sa1-217 Sa1-228 Sa3-110 Sa3-112 Sa4-26
Sa5-407 Sa6-123 Sa6-128 Sa6-307 Sa7-411 Sa7-414
Sb2-14 Sb4-30 Sb4-34 Sb4-38 Sb4-44 Sb7-208

red = the same type as Sb2-14

blue = the other type (though minor differences indicate that this other type really is not quite homogenous)

lilac = the rest
Sb7-223 Sb7-225 Sb8-21
