1211. An early Fyr Fyter fire extinguisher, text on it reads: "Wheel to fire, lower handles to ground, push down knob on cap".
1212. This was marked "sponge diver's spear", and that's the answer that I was planning to post until someone sent me a scanned catalog entry of a weed puller that looks just like it. I suppose it could have been used for both purposes. Also, it looks very similar to the tool in patent number 1,293,824.
1213. A Danlock, I have about twenty puzzle locks and this is one of the better models, not too difficult to open but a good challenge to get back to its original condition. The lock is well crafted and has a clever multiple move solution, I highly recommend it.
1214. A Scribe-Hook for Weather-boarding, patent number 72,885, from the patent:
...an improved form of weather-board hook, in combination with a fluid level, graduated rule, marker, and gauge, the whole constituting a carpenter's combined tool, of great utility and convenience.
