I have a question for anyone who has built either the ST #1 or the #5A engines. A good many years ago I acquired a number of ST castings including a #1 and a #5A. They were out of their original packing, in separate boxes but were essentially complete. The 5A had some machining done ( not particularly well done) but the #1 was untouched. I have started machining the #1 and having finished the big end bearings yesterday I started looking at the connecting rod casting and it seemed to have a lot of excess material to machine away, so I dug out the one for the 5A and comparing them both with their drawings it appears to me that they might have got switched. In the picture the rusty one on the left was with the #1 castings, the other with the #5A.( all the #1 castings had a coating of light surface rust but the #5A were clean) Can anyone confirm which one is for which engine? Thanks.

I think it is more to do with when they were produced than what engine they are for, currently both conrods share the same part number.
