I was restoring my battery box and had a five of these battery decals made up, I used AutoCAD and I think it is very close to the original battery placard found on most of the older 150s.

If anyone wants one of these just let me know and I can mail them out to you for free

If I run out, I can reorder these and get more printed up; they will only cost me about $2.00 each to print up another. 6.
