This isn't a big deal but I ordered three 8x10 BTZS tubes from The View Camera S tore a week or so ago at a cost of about $180 (got tired of the occasional scrat ch from tray developing). They arrived yesterday and I was surprised to see that they look nothing like the 4x5 BTZS tubes. They look like someone went to Home Depot or Lowes, bought some ABS tubing and caps, and put them together. They hav e industrial electrical or plumbing coding on the sides, no place to number them as you can the 4x5 tubes, and also are quite scratched up as though they've bee n used. The caps do screw on, which is a big improvement over the tubes I tried to make myself, and they certainly seem to be funcitonal but I'm just curous whe ther this is what the 8x10 BTZS tubes normally look like or whether I was sent s omeone's home made used tubes.
