When I was going through college in the mid-90s, I worked for OEM Tractor Parts, we made Farmall stuff. I took my ZTU battery box to our welder (who did all the Farmall fabrication stuff at night parttime). He loved it any MM stuff I brought him. The first night, he got his measurements and pattern. The second night, he had 5 of them completely cut out, bent, welded together and told me to go sell 4 and keep one for myself. The ZTU box is so much more complex than this one. Given the proper materials, a seasoned machinist would "probably" whip those out in a hurry if they had good measurements. I say respect the value of what you have, which I know you and all of us do, but don't be afraid of it. :) But I still say get good measurements off of it even if you don't make any others.

For the sake of you having an excellent pattern, I would draw up some measurement and sketches and keep them handy. I don't think anyone will find another one of those anywhere.

Would think to make one would be real challenge. Would be easier to drop electrics and use crank! Paint color not my choice for PG1. Too much orange.

Battery box is KT910 for ZTS and was also used on KTA and UTS. Previous JT number is for ZTU.

Yep. I’m working on a 1946 ZTS and the battery box is rusted out. Don’t see many good ones around.

Wow, I bet anyone who has a ZTS would love to have that. Nice find.
