There are some differences in N/S rail. The code 250 that I have seen seems
to be made of an alloy that is lower in Ni than the alloy I used for my 332
rail.
Aristo may have changed suppliers for the latest batch. Profiles have to be
very carefully drawn to match the profiles and tolerances set by the buyer.
Quality control has been a problem with many marketers with the switch to
"offshore" suppliers.
I have not heard of any pitting in my original 332 rail, and there was an
extensive layout in the LA area, although some was destroyed by a "volcanic
eruption" when a gas line going to a scale volcano developed a leak and the
accumulated gas exploded and did some extensive damage to the layout and the
side of the house facing the layout.
Some of my own rail on my track has been out since 1991. It has weathered to
a nice dark color and is still in perfect condition.
I'm sure Mr. Polk will rectify the problem with the bender/rail mismatch.
Please keep me informed.
Keep your steam up!
