Kit Items Value

Not sure if this is the right forum for this and if it is the wrong forum sorry and admin please move it to the right one.

But was thinking of maybe parting with some of my kit items that I don't use very often and was wanting to get an idea as to what they maybe worth.

Subal 6" Dome port

Subal 105 flat port with the nob on the port.

Both items are in very good shape.

As I said above not sure if I really want to sell them at this time but some RL issues may require me to.

Are these 3s or 4s?

The threes are all over e-bay-the 4s are more $ and are less available

Sorry, I left that detail off. They are Type 3 ports.

I suggest looking on ebay as they are very commonly priced out there.

Thanks, I will.
