190 series block casting number

[Walt Puryear]

Members of the 190sl group are aware that 190 series blocks are interchangeable with the sl cars. A question has come up as to whether the casting numbers are the same. Does anyone have a 190 series gas engine that could provide these numbers. It is located on the right front side of the block near the oil pan. A group of samples for the 190sl are:

yr - engine number ------ casting number --- part number

'56 121.921 6503634 ---- 121 011 05 01 --- 121 010 07 08
'57 121.921 5702458 ---- 121 011 05 01 --- 121 010 07 08
'59 121.921 9501042 ---- 121 011 11 01 --- 121 010 11 08
