Would you be able to use a jig in a press, possibly even an arbor press to bang out the series? (or fullering under a power hammer)
Not sure how identical you need the 140 to be, but it sounds like enough to use a forge, so you can get a lineup of pieces hot more economically that just oxy/acet, maybe even just a pre-heat before torching...
the iforgeiron.com blueprints may help you!
