Chris -
I hope Kenny's parts reveal something for you. The gold removable dispenser was not available very long, relatively speaking, and not used on many models.
To my knowledge, the gold dispensers were available in a couple 1972 and 1973 60-series standard cap machines, I believe one or two 1973 large cap machines, the 1974 60-series, the 1975 500, and the 1975 60 series standard machine, and that's about it. Prior to 1972 back to about 1968 these dispensers were bolt-on and not every-day removable as they doubled as agitator caps. The revised removable dispenser was changed to white for 1976. Most of the models above were good sellers, but that's not a huge time window when we are now 35 to 40 years later.
The gold straight vane agitator remained in that color until 1983, but I don't think any machines were marketed during that time with the SV and a dispenser.
If Kenny doesn't have anything, you might want to check with used appliance dealers who were around in the 90s or earlier, as many keep stock piles of parts like this and may not have disposed of the parts yet.
Again, good luck!
