Bill,
The flat area is actually visable in the first picture of the original thread...

Unmistakable.

I didn't read the whole thread but if nobody already mentioned it, that's a Marbles brand front bead. I've got one on a Super Fox and another on a Stevens 522 straight grip trap model pump.

Firstly, Thank you all for your comments regarding the gun! I closed the deal today to buy it. Knowing the changes to the gun were likely factory, swayed me. Although not an expert, I evaluated the pictures for several months before posting to this list; I will continue to seek documentation to substantiate the consensus. Will a factory letter describe the changes done at the factory, (December 1934 and December 1935), as per the Remington date codes stamped on the gun?
Additionally, the rib needs proper repair-any suggestions on who to send it to? Lastly, should I leave the double trigger repair "as is" or should something be done with that repair?

No, the changes in 1934 and 1935 will not be described. As for the picture of the rib, I didn't realize that this was the Cabela's gun.

I would recomend Brad Bachelder, at 616-459-3636 for both repairs. I don't think a letter will tell you about Remington repairs.

If you intend to have the triggers changed back to a single trigger I would recommend DelGrego without hesitation.

Leave the double triggers in there. They may not be factory, but probably are. However, they will allow you to shoot the gun. That is a big plus.

I agree with Bill wholeheartedly. I should have been clear... "If you absolutely cannot be deterred from changing back to a single trigger..." would have better stated my opinion.

Agree with Bill and Dean on the triggers
