OK, so I got in the car and went back to the office for you (Yeah right, thank god for webmail
)
From David at TB
"JR Gent vs Baron.
Baron has a 12 facet pen grip, JR Gent has a round grip.
Baron made in Taiwan, JR Gent made in Mainland China.
Baron is better plated , JR Gent is made in Mainland China with not as high level finish.
Baron comes with a rechargeable fountain pen pump piston, JR Gent does not.
Baron comes with a German Made Schmidt refill, and the JR Gent comes with a Taiwan made generic rollerball refill."
Having done both recently I can say that the Baron gives the impression of being a better product. My first JR Gent the thread in the cap failed within a couple of days, might be rough handling to be fair.
At the price I'll be sticking to Barons I think from here on in.
Hope that helps.
