Gents, I lost my cocking tool (no smart-ass comments, please). looked on the Internet and frankly don't trust what I see. It is for a 410-field grade double, beautifully refinished and reconditioned by Griffith and Howe, up the pike from me in NJ. I vaguely remember from an ancient thread on this board that one can use a particular size box wrench to do the job. That might work, but I would rather get something more amenable to this purpose. Any suggestions from a reliable provider would be appreciated.

Go on the LC Smith collectors website, someone there sells them.

Let's start here

An open end wrench that fits the cocking crank is in my experience easier on you and the gun. Parallel jaw pliers or a screwdriver can be used also. You can also take the locks off and cock the hammers on the edge of a bench.

For the interested, there are images of various cocking techniques, including with Mark's wrench under "Disassembly and Reassembly" in the LCSCA FAQs

The cocking arms is tuned DOWN to cock the hammer. I would suggest wrapping the wrench with electrical tape.

The one on eBay is very well made. I just ordered one but recieved two because the first was lost in the mail, then appeared a month after the replacement.

Thanks very much for your advice. Much appreciated.

I think Vintage Firearms in GR Mich sells them

I always just pulled the lock and cocked the hammer.

A 4" adjustable works better for me. The original cocking tool did not have the hole in it to slip over the cocking rod/s. The original tool was for cocking the locks when they were off the gun and works great.
