Mac:
Glad the piccies came through OK. I try to make them as small as possible for quick download, but if the connection is at all slow the dreaded No-Image icon will appear instead!

The pin-spanner holes you refer to are simply felt-tip-pen marks, presumably from the alignment process at ER Shaw's. I should have removed them before posting (with Adobe Photoshop!).

My intention is to thread the barrels sensu Ellis-Brown, and 'tin' them in with 95-tin/5-silver solder. I have used this stuff to re-lay ribs and it beats lead solder hands-down.

Its off-topic (apologies 1pointer) but I tossed up another yarn about hunting with the .577 Greener. Pretty sure I've already posted it, but just in case you missed it! Be patient: the pics should appear eventually!
