replace “box mold” with “frame” and markup as <tl></tl>
NOTE If “box mold” is used to translate the word “chassis,” then probably change to “frame” depending on the context; some cases may need to be supplemented with qualifiers, such as “casting frame."
Replaced all instances of "box mold" with frame.
Question for @ps2270 on fol. 61v: the vocab says (under 'chassis'): "Kept in French in p061v “Chassis des Allemands” because seems to refer to a “viewing frame.” (PHS, 06/23/2017)" but the latest translation has "viewing frames of the Germans". Can you arbitrate?
