Hi Dave,

Welcome to the forum.

Lovely guns, the HW35.

Personally, with the spring also being a little bent, I'd go for a new spring that comes with custom fitted rear guide and top hat, which should result in a much more refined firing cycle.

I'd prefer to keep it on opens for that proper "classic" feel, but if going for a new scope would lean towards a nice 32mm scope in low mounts, due to the low comb of the 35.

Enjoy and feel free to shout up with any further questions and to get stuck into all the fun on here.
