Hey there! I came across these the other day on craigslist and had to pick them up. Plus it was a good excuse to get out of the house. I have yet to take the backs off and peek inside, but when I put my ear up to where the tweeter and squawker should be there doesn't seem to be sound. However, they sound quite pleasant and listening to a sweep of the frequencies I can here to my limit of 16.5k htz or so. Anyway, without delay here are some photos.
I am a noob on the forum and would greatly appreciate help from the community. I picked up a pair of beautiful Model H speakers and would like some help. Links to pics are embedded below. Could use some help with the following: Identify Age - back label is too faint for me to make out serial number.

Is this an indication of a bad crossover network in the one reading 8.2 ohms? I think these are 16 ohm speakers and in an thread on this forum I read that 12.4 ohms is in the expected range for a 16 ohm speaker. I have two pairs of KG4's of different vintage that I tested with a meter and found the following: Pic of Kg4-WO label - https://app.box.com/s/yjb1ehejktf518hpnfh1xi86o75vdzr8 Nominal Impedance on label 4 ohms impedance measured on one is 4.5 ohm on the over is 7.9 ohms Pic of Kg4-Oak Oil label - https://app.box.com/s/3b8oakziy6e36budpnuz888gjlf87iq4 Nominal Impedance on label 6 ohms impedance measured on one is 4.5 ohm on the over is 4.6 ohms What should I take away from the measurements I've taken?
