I would look into it with a fair degree of caution because of their reputation. Also because of the harp’s age it will need to be considered as an individual instrument; not all harps age in the same way and at the same speed and not all have been equally well treated or maintained. It might be worth it if cheap enough, but may be hard to sell when you grow out of it.
I would consult Pilgrim about it and/or the technician who last serviced the harp.
