The seller has the transmission listed for sale on an internet site. I’d hate to post his photos somewhere else without his permission, out of respect. But the numbers in question are definitely stamped on the case.
However, the seller thinks it is fur an earlier truck, from the late 30’s. I recognized the number as being for the 41-47…..but wanted some other input before I bought it.
