Sorry for my really bad english language,I'm Italian...
I've lost the old post where I remember there was the answer to this same question.
I'm not sure, but IF I remember well, I read sometimes ago in this forum that in the first years Holland & Holland didn't really manufactured "in house" its guns, buying them from other manufacturers.
In this case, would you so kind to help me, telling when H&H started to manufacture its guns, and the name of the manufacturers that produced the guns in the first years, before the beginning of the "real" H&H production?
Thanks in advance!
