Hi Guys

Im Trying to sort out some modern day weaver style base mounts for above

At the moment my rifle is fitted with now old and obsolete Parker Hale base mounts, now ceased trading in UK....

The information I have as follows measuring up my PH mounts with digital caliper gauges :-

A22 Front Mount, shortest distance between hole center's .734.5" + .134" average screw diameter , makes center's (.868") ?? mount length 1.250" or 31.71 mm , width 19.30 mm....

A9 Rear Mount, shortest distance between hole center's .247" + .134" average screw diameter, makes center's (.381") ?? mount length .773" or 19.69 mm , width 19.60 mm....

If anybody could shed light on manufacture and part numbers of new mounts
I would be most gratefull, thanks in advance huey45

The front base hole spacing is about dead even with the Weaver base #46 which is what the chart says is right for a large ring 98 front. The #45 base is what it lists for the rear, but the hole spacing on it is closer to .481. There is a Weaver cross-reference chart that gives all base lengths ,thickness, hole spacing, and radius (underside), which is what it would take to see if there's a base that fits your specs. It may be available somewhere on line. I have paper copies at school but I won't be back there till Apr. 1st.
