I recently purchased two Irish army series pipes to use on alternating days. I thought that they'd be no nonsense non system pipes, but with an army mount and therefore might take a bit of abuse, while saving my better pipes for weekends, etc. However, I'm having terrible trouble with them. Must have smoked about 20 bowls in each and they gurgle about one third through the bowl. Because they are army mount, I sometimes remove the stem when they start gurgling and I notice a large build up of moisture at the end of the tenon. I then pass a pipe cleaner into the bowl, wipe the tenon with kitchen paper and then continue smoking. But this a nightmare! It detracts from enjoying the smoke!
