If you find a NM serial number prefix, those markings are usually always absent and the "GENESEO IL USA" rollmark still appears above the serial number on the frame. The locations are the bottom side of the dustcover and underneath the right grip panel on the frame. for example, in the Mil-Spec line, if it has a N serial number prefix, you will find "IMBEL BRAZIL" or "FI BRAZIL" laser etched in two places. There's essentially two common variants of this. That is one variety of markings that will show up on Springfield's G.I., Mil-Spec and Loaded pistols.Īnother is the "Geneseo IL USA" found just above the serial number. That is where the "MADE IN BRAZIL" rollmarks come from. Should > 50% be done in Geneseo, IL, then it does not require a "Brazil" marking. if > 50% of the work is done on one of their pistols in Brazil, then somewhere on that pistol it will be marked "Brazil". This comes straight from Deb/Vicky at Springfield. however, i was very disappointed when i saw "Brazil" engraved on the frames of mil-specs at my local gun shop.
