Hi Mark, i'll be damned
I fully agree with Jim ... last but not least .
Hardly shot towers were implemented in Portugal: i am still trying to find out if hot shot was used here; not impossible, though.
Not wishing to go off topic, but something that fascinates me and which i have not been managing to spot where i have read it, is that the "pointed" bullet was idealized by Da Vinci in the XV-XVI century, although only implemented just the "other day".
The guy was simply unique.
