Yes, there are CH like LJ sized Esties. Some where produced in Brazil see https://starfountainpen.com.br/a-caneta-esterbrook/ (use your favorite online translator for details).
Those seem to have black jewels but nothing precludes exceptions.
Brian Anderson in his web site also notes the existence of blue pastel LJ with black jewels.
There are also solid red/blue/black LJ size Esties from UK with relief (14C) nibs.
Not a full confirmation but yes there is a lot of interesting things in the Estie kingdom.
Antonios Z.
