Seaforth, from your list:
- a “T” on flat left side of the body.- Do not see it
- “S51” on the underside of the butt. - Yes, see pictures I posted
- “S” on the right side of body on the small flat area below the bolt head. - Do not see it
- 35596 should be stamped into the underside of the fore-end, probably lengthwise. - Yes, also has a crown-like stamp before it, coming from barrel end
- The scope bracket should have the rifle serial number on the left side above the rear mounting screw knob. The D may be above or to the left of the number 35596 - Yes, see new pic
- The magazine may or may not have the rifle serial number on its bottom. - Yes! Thank you, didn't know to look, I have it.

Some worn markings near the S51. Looks like a 37 then a symbol very worn then a 47 below. Looks like the was a star inside an oblong symbol between these and the S51. I see there's a couple of books on Amazon and Seaforth I'll be drilling down into your site too. Great stuff, thanks everyone. Roger I thin this is the picture you requested.
