Schanzen: Arneberg (Arneberget)

Well...

Seeing now that the year of construction for the hill is given as the 1950's, Undis Blikken's jumps of 23.5 and 27 m on the same day in 1931 must have been done on an earlier version of the hill. But I have seen men's hill records here as far back as 1921.

Hill records

After the hill was rebuilt around 1971-72, Arnfinn Kalfoss (Norway) set a hill record of 42.5 m on 17 March 1973.

There is also a possible women's record. Undis Blikken (Norway), who later became known as a speed skater, jumped 27 m on 22 March 1931.

Correct jump sizes

The hills at the time of the Olympic Games were actually not K-80, K-60, and K-40, but P-80, P-60, and P-40.
On a related side note, the 60 pts distance was defined (I guess) as the distance of the longest jump in a round (rounded up to a whole meter), so for the P-80 SJ it was 94 m in the 1st round and 85 m in the 2nd round, and for the P-60 NC it was 64 m in the 1st round, 69 m in the 2nd round, and 68 m in the 3rd round.

Name

I can't be 100 % sure, but it seems that the name of this hill is Pladsebakken, which was opened in 1975 with a K30 and a K15 jump.
