Bsf 45

And the 50. Only difference I can see immediately from the 45 is a cheek piece.

And maybe a longer sight rail, though that could be a function of lighting in the pic?

I thought the 45 & 50 had a shorter cylinder it would be nice to know for sure . Some one who is good at picture sizing could probably measure it accurately enough .

Scroll down for what I imagine is the catalogue referred to by AirSupply.

I’d never really looked that closely into the model variations, but there seems to be a theme here: a distinction between sporter/plinkers (simple stocks, elevation-only adjustment rear sights and, on the 55, shorter barrel) and more refined semi-target guns (longer barrels, cheek pieces, fully adjustable rear sights). Which probably made some sense when the range was conceived in the 1950s.

My recollection (vague) is that the 55 gained a windage-adjustable rear sight in the mid/late 70s.

Here is the 45 beside a Gecado/Original 25
The cylinder is shorter on the 45 and the gun overall looks a similar size.
I purchased these 2 rifles together and these are the photo’s sent by the seller.
Geezer I think your spot on with where this gun lies in the in the BSF line up. Spec’s for the 45 are also only for .177 so probably only produced in that caliber because of its power limitations I guess.

The catalog is pretty hopeless in terms of properly describing the different models! Could be another reason BSF are gone.
