Poor choice of words or the use of them by me. My other HVA sr is stamped on the barrel High Standard model H-100 both have the same barrels length and contour. Somebody in the past removed the ramp frt sight off the 51-l but the rear sight is in place but taller than the one on the h-100. The 51-l has a monte carlo sporter stock with checkering where as the h-100 has straight stock no checkering. I imagine there were other HVA sr action used on other brands maybe. Be my guess both have exactly the same barrels by High Standard I believe they were chrome lined? Mb
I know for certain the model 50 & 51 were barreled by High Standard and had chrome lined barrels. My 51-L however came to me sans barrel. It's cool that you have examples labels as High Standard and JC Higgins! also nice to know barrel contours were the same. Good info, thanks.
