I too have one of the above, S/No:1458886 purchased from JSR. I too like the natural wood grain laminated stock rather than other specials.
I have total number down as 163, with two lots of batch numbers, as there were initially only supposed to be 100 made, but extra stocks were produced leading to extra rifles.
Batch numbers were: 1458842 - 1458941 and 1459688 - 1459752
