H&R Topper Longbranch?

[bill c68]

Picked up a single shot 16 today, H&R Topper made in Longbranch Ontario. Very neat looking gun with some unique design features. Does anyone know much about these? Are they worth anything to collectors?

I just bought one in 12ga recently. I got it partially because it was made in Canada but there is no big collect market for them. My research shows that most of them were made in the 50s and 60s. I have it as my only shotgun and so far very happy with it.

Would also like to know any additional info.
