Rob - I would advise against top-coating a finish from 1925. As the older finish starts (continues) to craze it will telegraph up into the newer top coats. The only route I would even consider besides leaving it alone (preferred) would be to clean well and apply a high-quality paste wax. Unlike Howard's Restore-a-finish it actually provides some lasting protection for the existing finish. Any damage to the wax film is easily remedied and renewed.

It was well cared for and largely sat untouched for decades. Although the finish is in excellent shape it will eventually have issues due to age. I'm wondering as an alternative to striping off a perfectly good looking finish, maybe scuff it up with fine paper and pads and then shoot a new clear finish over it. This would make the finish hard and smooth again without having to deal with all the stripping mess, grain filling, color matching, everything from scratch. This could reduce a two-three week job into a matter of days. Has anyone here done this or seen some disasters? Any suggestions?
