I found a cockshutt 1755 that i want to buy and was told it had a perkins diesel in it but i swear it is a 310 waukesha, the serial numbers on the top of the valve cover are 163-194A and 223-139.  On the side of the block the numbers are 221620 and 165425A, on the front of the timing cover they are 163968A and 191945 any tips on what it might be, i'm thinking waukesha but want to be 100% sure Because i have not been able to find any information on it
