More like a 6xx series.
I have a shower only set up and I think it must be a 1600 from all the research I have done but someone who has seen this before would know better. Is the only difference the 600 has the tub portion? THey both look the same otherwise to me. Can I use a 600 renovation kit to get the venitian bronze if it is a 1600 or am I stuck with replacing the whole thing?
The 1600 uses a rotary motion and you can only control the temperature with the handle. Yours is a 602, or similar, which controls both the temperature and volume with the handle.
