I managed to find a 60 amp ammeter with the tulip head. BAS is charging extra for patina. In faint print on the outside of the case is stamped “95367”. In very small print at the top of the dial is printed “95397”. Mine does not have an external shunt and it looks like there is one on the BAS unit. Any idea on where to find a suitable shunt?gfeher wrote:On a hunch, I was able to find a page from a 1949 Stewart-Warner catalog showing both the 30-0-30 amp ammeter originally used in C-170 models and a 60-0-60 amp version of the same gauge. The 30-0-30 amp one used in C-170 models is Stewart-Warner p/n 95245. The 60-0-60 amp version is Stewart-Warner p/n 95367. I've uploaded a pdf copy of the catalog page to the MX Library. Gary, you owe me a beer for this one. I'll collect it at the Cody convention if you are there.
I also noticed the catalog lists the 30-0-30 ammeter as p/n 95245. My 30 amp. gauge looks to be original and has p/n 95269 it fine print at the top of the dial.
