Sorry to bump an old thread, but it seems we're in a new world....
I tried to get Benjamin Moore N333 from two local BM dealers, and each told me a different story (different levels of competence of the employees at each, I believe), but it seems that the N333 is no longer available under that code number (or perhaps at all), and even if you could special order it as a base, you'd need a tint component, and that is also an unknown (it used to be said that "02 Bright White" was the premix colour, but now it seems everything's changed at BM). Does anyone have any real-world experience with anything current that is "the same" or at least "close enough" (I'm talking about 99.9% close) to match an otherwise matched kit? Jaghog, you said BM alkyd - do you know which one you used? Semi-gloss white? I've emailed Jack Lawton, as I figured he'd know if anyone would, but I've gotten no response yet (I know, he's a busy man), so I wanted to put it out there, here, especially since things seem to have changed, and the common InterWebs answer of "BM Regal Semi-Gloss N333" no longer appears to be "gospel."
This is for a '66 (I believe, if it really is a match for the other drums in the kit - the date code is obscured as you'll soon understand) silver sparkle 22" kick drum, which a previous owner decided to "doodle on" all over on the interior in a variety of ink pens. I've tried removing the ink using all the usual no-invasive methods, but it appears to have impregnated into the paint, necessitating a sanding through and repainting. Fun. Real fun. I'm only willing to go through all this trouble because it's clearly an original Hollywood kick and otherwise undrilled/unmolested drum, and by all evidence and accounts it's the original match in the set with at least the top toms (I believe the 16" floor tom is otherwise, but that doesn't bug me)....
