49" would be considered an upright really, without the console or certainly the so called spinet designation. Consoles range from 40-44 inches.
The hammers are probably sticking or else they need backcheck adjustment ( hammers resting where they backcheck to when you play vs on their rests or near their rests. Sometimes just playing can bring it out of this condition. My thought is the piano should sound on the mellow side of bright. I see the felts are grooved and maybe compressed a bit which would brighten it up if anything though. They could use voicing but if you are happy with the overall sound don't pay to have it done. When voicing, a tech would sand the hammer felts down to smooth and round again and maybe pick below the surface a bit to get an even sound across the whole keyboard. No need to pay for that if you are happy with the tonal quality.
The sound that is off now could be , most likely is, because those hammers are not throwing against the strings correctly from the position they are in. Not to mention a little tuning. But tuning and those hammers being out of place are not one in the same thing. So in other words, this could cost a bit more money to get straightened out than the cost of just a tuning, though it may well come under regulation . But uprights tend to do this more so than grands because of the position of the hammers being upright and a grands laying down, they really don't have to be very sticky on an upright for them to not return fully and that's most likely what is going on vs the action being worn out, for instance.. If just sticking a bit you can probably lightly pull the hammers back into place. If there is a mechanical problem then probably not able to lightly pull them back into place. Another possible cause is one hammer is rubbing against it's next over mate. Just touching enough to hold it back from returning. Sometimes the hammer shanks get a little wrp in them or curve pushing the hammer itseld out of alignment. Without physically seeing the piano in person I can't really say which situation is the cause.
If you feel uncomfortable about this call a tech and see what he has to say ( you need one for tuning anyway, maybe he will come out and have a look for you). Where I do my own work I would not hesitate to tackle this as long as those stuck hammers move and the keys are not stuck as well. Although I tend not to work on uprights anymore.
One last thing. Tuners/techs often have several contacts for used pianos they have worked on if they don't even have one themselves they may be rebuilding or some such thing. That's how I got my grand piano was through my original tuner, he was doing a partial rebuild on it in his basement. The second tuner I used rebuilt pianos as part of his living, still does. When I get stuck on something I still call him, mostly for advice. Chris and I are friends, he and his wife had been to recitals of mine and myself and my wife to recitals if his etc.., though quite in the past at this point ( heck my oldest daughter was ready to graduate high school about then now her second son is graduating college this year !).
