35mm Combo: What could I ask for it?

[raid]

I have a very clean Summicron 35mm/2 version 1 with goggles. It had only one previous owner who bought the lens when he was stationed in Germany. The lens is near mint [in my opinion]. It is hardly used. It comes with the original box. I also have a mint 35mm Brightline Leica viewer.It is the original first one that is yet unsurpassed.

I am now for the first time interested in selling this set. Could you give me an idea for how much I could sell this set.

I was once offered $400 for the 35mm viewer.

Raid, I don't see why anyone who takes the goggled Summicron will want the SBLOO as well.

This is a good point; I just want to replace both items. Maybe they should be then sold separately. Thanks.
