Lyman 35 Receiver Sight question

My #35 is as yours and too, my bit of Hans Tascher #5 Catalog, N.Y. the same illustrations. My Obie Model M bearing it is one from the first month of the first year of Mauser production, Dec. '13; SN in 78K I believe it was a Tascher import.
You may be thinking of the Lyman Model 36 for the Mannlicher. The diopter arm swings gate-like to accommodate the bolt travel. Pix of one below on a Model 1952 in 7x57. At about $500, the sight now values at more than I paid for the rifle... in the dark ages!
From the prior blog re sight hoods. I've seen a few Obies offered with hoods. Some postwar made FN commercial '98 rifles are yet with hoods and that patter will supposedly fit the prewar Oberndorfs. The style is of the compounded-contour hood with the uppermost portion of smaller diameter. Frosty has such pattern shown in his pix offering.
I suspect they may have been made by Oberndorf, but 'if' furnished, more often as accessories. They don't survive for the same reason most don't on the high power bolt rifles; not popular! All pre '64 Model 70 rifles came with them, few survive on the rifles!

Bit of trivia, my type M of 1923 in '06, SN is shown below. Is yours 87505? Mine as yours, but original sights.
Best!

I had a Lyman folding peep on a M-S Model 1903. I gave that rifle to my son. The sight was quite the gadget, an overcomplicated compromise, like most accessories for the M-S. I am fond of the Mannlicher-Schoenauer (my grandmother was from Steyr) and I still own one M-1903, but I am aware of their design deficiencies.

The great thing about the Lyman 35 for the Mauser 98 is that no modification to the rifle is necessary, no drilling and tapping and only a minimal shaving of a sliver of wood from beneath the bolt stop.

The first Lyman advertisement (see below) shows a Lyman 35 without the click adjustable height dial.

I found pictures of the Oberndorf Sporter compound contour front sight hoods in an old Mauser catalog. I now know what to look for but not sure I will find any.

The serial number on the Type M 30-06 in my photos is 87505. Only a few numbers away from yours. Probably made the same day?

Thanks for the SN info Robin! Really "small world" as conjuring possibility of rifles made the same day or so, same point of origin, onward to ultimate dispositions half world away and presumably two nations apart as celebrating these rifles Hundredth Anniversary of Mfg. Current owners "connecting"! "Clink, Clink!"

Then too, huge odds of my two consecutive SN dated 1913 vintage Model "M"s 'connected' in my hands as sourced about thousand miles separated and almost two decades in time apart! Their 110th Anniversary this year as only some months "new model" production halted asr most German mauser sporting rifles. WWI military production demands intervening for War's duration.

Moment of waxing "era nostalgic", conjuring ironies! The eve of World War One; British Foreign Secretary Sir Edward Grey's remark "The lamps are going out all over Europe and we shall not see them lit again in our lifetime." A Century later same fashion war of aggression again raging in Europe on largely the same battlefield tactics as the lights going out in Ukraine without end in sight... Incredible!

Re that Mannlicher Lyman Model "36" (I've corrected my above Post). I agree exactly with you. A "gismo" of complexity. Yet 'working' and of Lyman quality! They're incredibly expensive devices on today's market. Just such sight as ours, more than I paid for my entire Model M bearing it!

Thanks for posting another of your nifty rifles!
Best!
