The pipe had only a brief stay in Singapore. I'll take it to Australia when I return next week. I must admit, I wasn't overly impressed with this particular item, and I wondered what I would say to the security guards if they asked me about it on my way back onto the mainland. (The cache I found it in was on Pulau Ubin: an offshore island belonging to Singapore.) Remember, it's "Death to Drug Traffickers in Singapore"! They take a dim view of drugs generally here, and an opium pipe might rais an eyebrow or two.
If I find something black, I'll swap it over and post the pictures here.
