The build numbers are actually quite close together. Fisher Tank Division was making 400 to 500 tanks a month on that one contract for 2000 M4s, and 4600 in just over 2 years on five contracts, out of a US total of 49,000-plus produced. When they got rolling, the daily through-put was staggering! Other more well read historians than me, come back to the high standardization of parts and components as central to US wartime production. If a shipment didn't meet inspection standards, it would be refused. If the supplier kept shipping bad parts, they'd lose their contracts. It wasn't just tanks but rifle parts to airplane parts.
