The 1-2 mike is not worth a lot, lots of them out there on E Bay, and that one looks well used, having so much missing paint on the frame, the other items are looking nice, but I see only one rod with the depth mike, that limit's it's value; are there any more rods in the box under the paper? The inside mike set is quite nice, I'f look up the items online or on e bay as completed items, and get an idea as to value. I dont think the 1-2 mike would be worth more than perhaps $20 - 30, the other items likely about half of new list. The items are in nice condition for the most part, but we must consider that with manufacturing so far down in the US that there is a great surplus of such tools on the market, and hobbyist folk are not, for the most part, given to free spending.
