About this machine
Brother identifies PC420PRW as a discontinued sewing machine and documents three built-in lettering fonts: Gothic, Script and Outline. Brother's replacement guide groups PC420 and PC420PRW with PS500 as the replacement. That listing does not establish identical specifications for PC420 and PC420PRW.
PC420PRW needs evidence separate from PC420
Brother support explicitly covers both PC420 and PC420PRW for the three lettering fonts, and Brother's replacement guide groups them together. That relationship is useful context, but it is not enough to copy the entire PC420 specification table onto PC420PRW.
The three font names are confirmed directly
Brother Support names Gothic, Script and Outline as the three fonts on PC420PRW.
Do not use family similarity as a substitute for a manual
PC420 has a rich official product page, but the PRW suffix represents its own model identity.
