Interesting S'G' Trigger Housing on Ebay

[kar66]

IP/S'G' have several unique features that the one on e-bay is lacking. JimF4Ms photos show them quite well. The bottom one is a classic IP/S'G' triggerhousing. The top one is one that has always puzzled me but no doubt is still a S'G' triggerhousing. They are milled on the side like SG housings but have all the other S'G' features. Almost like SG sent S'G' a partial finished housing that S'G' then finished milling. But I really don't think so, but I really don't see S'G' changing how they were milling the sides for no reason either. Now to the one on e-bay I don't think it is S'G' at all, it doesn't have any of the S'G' unique features. You can see it has been heavily sandblasted and I think somebody added the 's to the SG markings. The rest of the parts maybe OK. But no way would I pay that much for that triggerhousing.
