With tongue firmly planted in cheek, St. Paul Steam takes us back through the history of Jensen safety valves ... and well beyond !!! ;c)
Just be careful not to overtorque that last one ... it could strip the boiler threads.
Bruce, ya got me there with the last slightly over-sized safety valve...awesome piece of work!
Rog
this falls into the "why not" category

Looks great on the vertical/flat topped boiler
That huge SV does look rather good on top of the #30, but it also looks a just a bit like the aliens have landed. ;c)
Thanks for the history lesson...2 years old 
That gave me a good laugh Bruce, well done !
On the same page, does anyone recall the great sound raincaps make on a Jensen 55 with truck exhausts added?
