The MS takedown system is rather similar to that used by Westley Richards in the early twentieth century. They were not, though most or all that I have seen bear British proofs (does yours?) and several 'bespoke' British retailers had their own 'break open' versions.

Several references of decades past referred to them as the 'British Take Down Model' with some indicating that they were converted to TD in England. Before the internet they were little known and many otherwise well informed people insisted they did not exist or had been modified. For months none will be seen and then there will be a few available at once. They seem to run 'feast or famine' on the internet auction sites. The Take Down Model has great 'gee whiz' factor, the tang groove arrangement adds additional strength to that crack prone area of the stock, and is convenient for travel.

For 'real world' price comparisons, scour auction sites worldwide. That truly comes down to how much it's worth to you. Their lightness and balance makes them superb light 'brush guns' or for the stalking mountain hunt. The pre WW2 Mannlicher Schoenauer is considered by many to be among the finest sporting arms ever produced. If all is well with the rifle, $1,000 USD would be bargain basement, could go $2,000 or better depending on condition. also adds points for originality, though it's nice to have a removable scope (my cased M1910 TD has a claw mount Gerard B).

The apparent fact that it has not been cut for a scope. The fact that it is an original Steyr take down adds considerable value. Though the most common pre WW2 MS, they are highly sought after. The M1903 is the most popular MS as it uses the available 6.5X54 cartridge, though it is still better to make one's own as cartridges must be of proper length and overall profile in order to work flawlessly through the wonderful Schoenauer magazine. Though not much can be discerned from the single photograph seems to show a nice, original, M1903 Take Down. Sight leaves can also be found or fabricated. Reproduction rod sets can be found, there are presently two sources for reproductions on Ebay. The light colored stock is somewhat unusual, but not unique and possibly the original finish (they are usually much darker).
