I recently purchased a C&R BNZ 1941 MP-40 for $18,500. The price is a bit high despite the fact that the bolt and barrel are not matching because the bluing is original (with rust flecking from age). However, it is a rare MP-40 because the original hook style bolt handle, and not the 1942 improved bolt handle with the built in bolt safety lock found on 99% of all MP-40's. Almost all MP-38's and MP-40's were modified with the new style bolt handle starting in 1942, making ones with the simple hook handle very rare today.
