Estate pipes and Stand Gift

My daughter acquired a small collection of estate pipes and a stand from a nearby garage sale and gifted them to me for Xmas. There are some unusual looking pieces in here so I thought I'd share.






^The set, and the stand. Holds 10 pipes.




^These two are very nearly identical in finish and design, with the second one being slightly smaller. There are no markings or identification on either one, not even a symbol on the stem.




^These two are very unusual looking. The stem is metal and has cutouts, and is completely open and relies on the filter inside to keep the pull of air directed through the bowl. Very strange indeed.

(marked: Medico, ventilator)


(marked: Milano, 39)


(unmarked, save for tiny circle on stem)


(marked: Medico, Appolo)


(marked: Yello-Bole, Imperial)
So what do y'all think. Some unusual pieces in there for sure. A couple of them need some TLC for sure, but they all look serviceable.

@rcstan: I had just finished giving the insides a good vodka bath after Kalashnikov Day (Dec.23) activities. Even if I wasn't airing it out, I seldom use the mechanical safety on it but rather rely on the primary safety (user discipline).
The Milano and the Yello-bole are my two favorites as well. The Milano unfortunately has a broken stem. The pieces fit so nicely together though that you cant tell, and I'm pretty sure I can adhesive the stem back together to be usable, but doing so would render it impossible to remove the stem for cleaning.. Not sure what I'm going to do with that at this point.


The Yello-Bole was obviously the previous owners favorite as well. It has a very thick cake built up, which has an amazingly strong aroma sitting on my desk.


Also, I posted this little pipe as being unmarked, but in the sunlight I was just able to make out a marking that says "Slimfellow". This is a nice little pipe and will likely end up being my new driving pipe.
