Anybody ever run across a Keystone water heater? Made for Crane - copper tank. Serial number 2393660. Any information?
Thanks |

I have inconsistent information on them, but the great supermajority of the seven-digit numbers seem to start with week-week-year-year, so I believe yours is the 23rd week of 1993.

Thanks Russel, but I believe it was at least 25 years old - hoping for confirmation, but not concerned about it.

Thanks for that David - this one may be the oldest I've seen, don't know that it worked because the gas was off.

The last confirmed Crane that I have in my records is 1997, confirmed by the ANSI date. The seven-digit serial numbers for Crane were used ca. 1984 (that's the earliest I have) to 1997 (that's the latest I have). Everything I have indicates 23rd week of 1993. NACHI 2005 U.S. Member of the Year

This leads me to that belief:
Patent numbers from 1920s and 1930s. |

Example of write up if you can not find sufficient supporting documents of age:
Keystone water heater - Crane. Serial# 2393660 We were unable to find supporting documentation to verify date of manufacture. Water heaters have a life expectancy of 9-15 years that generally can be extended with proper care along with manufactures maintenance suggestions but depending on use and water condition or makeup. Due to the vintage look of this unit, we anticipate it to be over 25 years. Budgeting for repairs or replacement should be anticipated. Peter Doane Realty Check Inspection Service NACHI ID# 05120681

There are many items in today's world that are based on very old patents, such as light bulbs, for example, and if you were to actually look at, say, computer equipment and software and then go look up the date that all those patents were acquired, you'd find a lot from the 1950s, 1960s, and 1970s, yet the latest version of my software is Copyright 2008.

I did not say that patent numbers have lead me anywhere. Thanks anyway.

1. Good Housekeeping Seal - since 1909
2. Copper 3. "Automatic" 4. named "The Keystone" 5. 1920's and 30's patent dates It is way old, or a clever forgery. |
