Pats, just one more piece of friendly advice
.
Look at this thread where Don explains how to report OOB errors.
You aren't far from it, so if Don and Andy want to take account from your corrections (which they'll certainly do once they are back on the job in one or two months), they should have most of the data they need (OOB number, unit number, value involved, corrected value).
Once again, don't expect a positive feedback if you just say "some units" are wrong, better list the unit numbers yourself and better still, find a date of introduction of the SIG-550 in the Chilean forces, or Swiss forces at least (I know you have that one).
Just a thing about SIG rifles. Isn't "SG" the standard naming for them? I have often seen them called "SIG SG-5xy", probably for Sturmgewehr?
If I'm not grossly mistaken, it could be what it is about.
And what about the SIG-510 and 540? As far as I know the 540 series are a totally different thing from both the 510 and 550 series, and I've never heard of SIG-550s in Chilean service. Looks like the 540 (license-produced by FAMAE so more adequately called "FAMAE-540"?) is still the
main assault rifle of the Chilean army.
Thanks for the indexes of SIG rifle LBMs, I hadn't found these yet!
