LD, If you read my post I did say that the R-10 and R-1 have similiar looking stocks. However, thats where the similarity ends. The R-10 internals are quite similiar to those of the R-9, as I said, except for a slightly more powerful spring. The receiver tube is the same size as the R-9, and the springs are interchangeable.
The R-1, however, has a 30mm tube. It's actually a build-up of the HW35, with extended tube and longer spring. The spring is much too large to fit into an R-10. The R-10 does shoot near 925 in .177, but the R-10 is a much more robust gun with more durable internals. Overall its superior to the R-10.
on the left is an R-10 tube, on the right is a HW35 30 mm tube, same size as the R-1. Theres is a significant difference in size.
As far as which gun is which, HW has recently revamped its model designations and to some extent has changed some of its gun designs. After a bit of asking around, heres the way HW has it now as near as I can tell-
The new HW85 is the same as the R-9, but the HW95 is pretty much the same as the 85(??) so its also the R-9. I haven't been able to find a suitable explaination as to why theres 2 nearly identical guns in the line-up. Both have the same powerlevels, internal parts are interchangeable, they look similiar externally, theres not a lot of difference. The only difference between the 85 and the 95 seems to be minor stock design and maybe barrel length. Everything else seems identical. So, as to which is the current R-9, looking at the two side by side I couldn't tell you.
