ILION'S ARCHIVES: Remington 550-M ??????????

[usabaker]

Is there a listing of the Remington firearms that have been part of the museum and ILION'S ARCHIVES? I've collected a database of more than 1024 Remington 550 series rifles, and I have seen a lot of interesting rifles, but one that has just been put up for auction on Gun Broker has really put my brain on overtime.

This one is listed as a Remington 550-M. It doesn't have the 550 buttplate, the crown is flat, and the rifle is outfitted with Redfield target sights. I first thought someone just took a tool and made the "I" into an "M" and made their own custom 550 rifle. But then in the text it says the rifle is from the "ILION'S ARCHIVES"

Is there a way to validate this?

I'm in the middle of writing a book on the Remington 550 series of rifles and this definitely raises some questions
