There are several variations of non-Pars import Portugal receivers that I've seen or found on the internets.
I have or have held in my hands the following three types:
->virgin receiver: 91AExxxx Interport, Delta UT, Portugal - marked on right side magwell (havn't seen a serial number below 200)
->virgin receiver: 91ATxxxx Interport, Delta UT, Portugal - marked on top (my serial number is under 100, and so is the OP's, so there may not have been very many of these)
->receiver with trunnion and cocking tube welded on (but welded where?): marked "FMP" on left side magwell (nice deep stamping), Inter Ordnance of America, Monroe, NC(?), made in Portugal, 308 win on right magwell (not as nice or deep), and 7.62x51, SLG95, and serial number Axxxx on the top (in nice deep markings) Note on these: I have my suspicions that these may have been welded in the US. Mine has the barrel pin hole drilled all the way through, whereas a virgin trunnion would not have that, and the cocking tube is tweaked at the end. I suspect that these may have welded in the US with surplus parts, but I have no way of knowing or confirming that (at least until I get the trunnion out).
Not seen personally, but found from various internet searches or pics I saved:
->On Gunbroker:
-Indep, Portugal, G-3, imported by CAI:
->An a pic courtesy of the VPC folks (nice of them):
Question for the experts: Where complete SLG95s imported from Portugal?
Or where they assembled here from parts?
->Don't know anything about this one, but from this thread:
