Thats not even a WWII German Bird. The Messerschmidt used an inverted v-12. the HA-112 Buchon was made in Spain after the war.
the dead give away is the exhaust pipes are too high. its a standard V12, not an inverted one.
This is an imposter and hardly worth half what they are asking.
For comparison, this is a picture of an actual Messer. 109
