Travel Mini Espresso Maker

travel espresso maker

Hello fellow coffee lovers, bought a mini stovetop espresso maker (not a gsi) from a second hand store. It holds 4 ounces water, flared bottom, straight sides and a the lid unscrews with a filter inside and a spigot shooting up about three inches with a hook where the coffee shoots out. There is room on top for a small espresso cup and it isn’t lipped like a GSI. The filter doesn’t remove from the lid and I’m wondering how it works. Any ideas?

 I’m unable to find the maker online and was wondering if anyone out there does know what kind it was and what type of filter it needed?
