I have a 1903 Model MS takedown rifle in 6.5x54 MS. If possible I'd like to discover it's year of manufacture but so far that information has eluded me. I was hoping someone here would be in a position help.

The rifle has numerous numbers and markings but nothing that appears to suggest a date of manufacture.

The numbers/markings are as follows:

The front receiver ring is stippled on the upper surface and marked Patent Mannlicher Schoenauer M. 1903

The left side receiver wall is marked Oesterr Wappenfabr. Ges. Steyer

The underside of the breech has the letter T enclosed in a circle. This mark also appears on the underside of the receiver.

The breech and receiver are both numbered 5954.

The opposite side of the breech appears to me to have a number of, what appear to me to be British proof marks. These include an arm holding a scimitar/sword above the letters NP, the letter P (in the style of the @ symbol with a crown over it and the letter V with a crown over it. The breech also has the words Nitro Proved written on it. There is another mark in the form of an animal, possibly a hind.

Does any of this help those of you who have an understanding of these matters?

Thanks
