Well here it is all done.

My 1922 6.5x54 Mannlicher Schoenauer M1903 'Takedown' with it's 8x56 Schmidt & Bender with 30mm tube ready to go.

A brilliant job with exactly the right parts & set as low as it can go to allow minimum barrel clearance and the wing safety to operate.

The exact info for this job is as follows:
So, the scope to go on my little beauty is a Schmidt & Bender 8x56 Klassik, 30mm tube, with the part numbers as listed below in case anyone should be thinking to do the same with a similar rifle, this is what will work and the scope will be mounted to give the lowest possible viewing height.

Front dovetail half saddle mount (in the white & requires blueing/blacking) located in front of the rear iron sight - Recknagel 50000-0617
Front dovetail claw mount fits into the half saddle mount - Ziegler Z238ZG0301
Front Objective scope ring - Ziegler Z075ZA0562

Rear locking base mount (in the white & requires blueing/blacking) - Recknagel 53035-0000
Rear scope ring with extended base Recknagel 56000-3026 - this requires milling to correct height and fitment into base mount (also in the white & requires blueing/blacking)

The total cost of these parts in the UK has been just short of Ł400 and are only available in the UK via the manufacturers main importers.
The work was done by an engineer at my place of work under my instruction/direction and then all the metal parts sent away for blueing/reblacking. The reason for doing this was after the polishing and cleaning to solder the front base to the barrel, it all looks rather messy and requires a near complete re-finishing. Looks great now though.

Finally, the end result is - I got the exact scope I wanted onto this lovely rifle while also preserving ALL the original manufacturers engraving work untouched. Magic!
