They look like Crystaltone Gretsch snares. One is hammered brass. I have one just like it but mine is 5x14. The other is steel shelled. Although they are not sought after by collectors because they are not vintage they are very good drums. I bought mine in 2004/2005 and it is very heavy and very well made. It's Lightning throw off and butt are very simple but work flawlessly. The sound of my brass drum is what you expect a brass shell to sound like. It's sensitive and tuned down it has that clank you get with a brass drum. It has a warmth that is fun to play and with the die-cast hoops you can do awesome rimshots and it is LOUD. Plus with dc hoops you always get a nice cross stick sound for country and jazz or folky stuff. It isn't my favorite drum but it is a great all around snare. Depending on the price I would say you can't go wrong. It's also prettier in person. The hammering looks to have been done by a machine as they are large, pronounced marks. I always get complimented on it's look and sound. It's very sharp sounding when tuned tight. Think Stewart Copeland ala Spirits in the Material World. It has good bite and no one will complain they can't hear your snare. I use a thin bottom head and an ambassador on top and it is good for any style and is a versatile drum. I wasn't sure about Crystaltone at first. They are made overseas I believe but they are very high quality.

The guy sell them at 150€ per piece. It's not too much for a snare..

I would pass on the steel shell but definitely get the brass. If you don't like it you could get as much for that on eBay. If you are looking for a steel snare too then go with that as well. I have never played their steel snare but I am sure it is awesome too.
