New old stock SIBA black box cover. This OEM part is 55 years old but is new and unused. It has some small storage marks but retains the important embossed SIBA image. These are hard to find in any condition. Fits all Messerschmitt KR200/201 but was original equipment from 1955 to 1958. Many Bosch systems were converted to SIBA as the two types are fully compatible.
