I am renovating my late fathers Stuart v10 engine so its at least 50+ years old. Is there a way of confirming the age of the engine. The reason I ask is that the studs and bolts are of uniform manufacture including thread length for each item – not expected if made individually.
All threads were BSW
the smaller being 3/32 x 48 tpi
the larger 1/8 x 40tpi used on the piston rod and also on the eccentric strap and valve rod. I am told that most fixings should be 7ba.

An engineer who viewed the engine noted many subtle differences in the castings and commented that they were 'rougher than ones he had worked with and could see no reason for the use of bsw threads unless this was an early model. Any help appreciated

As Stuarts supplied all the fixings and still do they would be to set sizes, I believe Whit was used on the earlier ones but I don't know when they went over to BA
