It is hard to say as all of these changes were make well prior to Sea Sure taking on BLT. Looking back through the historic drawings the material was DZR1 as far back as 1991. We don't have any drawings previous to this so it is hard to pin point a date as to when the change was. I would like to be able to give you more information as to when the change was and the full reasoning behind it however this information has been lost over time. Our last original Blakes employee retired this year after 30 years with the company however he worked within a different division so also didn't know this information.
Our plans for next year is to update the BLT website so that all of this type of information is available as we know there are many people out there who are interested int he product and its history.

Thanks very much for this. As I am particularly interested in this topic I have investigated it myself. My Blakes seacocks were installed in the boat in 1984, which coincides roughly with the date that DZR was introduced by Blakes. They remain in good condition. I have read an account stating that 60/40 brass was used for a short time, maybe three years, prior to this but I have no idea whether this is correct. The Copper Development Association issued its first standard for DZR brass in 1980, although it was in use prior to that.
