There use to be another website that had tonnes of the Post WWII offerings. If indeed shooting steel, I would source one with good steel for the period and quite thick tubes which can be opened up..... After WWII, all the gunmakers were consolidated under the same umbrella to make War reparations for Russian elites & Hunters. So, for the most part, almost all are the same...
Although I have not used steel, but I have been pleased for 20+ years with tubes stamped near the lower rib >>Simson - Special Gewehr Lauf Stahl SP1<<, which @ one time used the 4 Ringe Olympic Style Stamp and at one time, we thought we knew the steel origin, but the origin seems to have been masked and maybe it was just advertising....
