Latest known serial number for Service Six?

[stonebuster]

I'm in the process of buying a very late production Service Six 3" 162-534xx which is about 1300 units prior to the last known Speed Six.(according to what I read here). Anyone know the latest known Service Six serial number?

According to the Red Eagle News Exchange,, the last serial number is 162-547xx. That's all I can offer.

When you plug that serial number into Ruger's serial number lookup page, does the page happen to tell you what model number it left as?
A couple months ago I discovered that 162-54732 is probably the highest serial numbered Sec. Series revolver. It is model number 1680. Not sure what configuration that is though.
Going from 162-54701 through 162-54732 the following model numbers are represented...
1604
1633
1635
1662
1665
1675
1676
1680

Only the 1604, 1676 and 1678 are .38 Special.
Again, not sure what catalog numbers these model numbers represent
