Welcome to the world of vintage drums. Sorry to hear the saddest of news, but it is the way it is for all of us, my condolences.
Those are some very nicely kept drums, it appears. In order to get a better "appraisal", if you will, and this is not exactly a "legal" appraisal for insurance purposes...it is only our opinions, we will need to know some specifics, like are there any "mods", additional holes from such mods, lifting seams where the wrap comes together and much more detailed photos...but all in all, those appear to be in excellent shape, thus far.
When uploading new pix, try to include shots like any damages you might notice, the "strainer mechanism" on the snare drum, (not the little wires, the actual device that moves the wires up and down) also known as a throw off lever, any pitting on the metal parts, any missing hardware, such as hoops or rims.
Also, if there is any stands, they will need to be documented and the brand(s) of cymbals. In this era your drums came from could have some of the very finest and most sought after Zildjian cymbals, or not. It just depends on what they are.
Please take some very detailed shots of any stamps or inscriptions on them, and note any damage, such as "keyholing" at the bell, cracks and "flea bites" at the edges. Cracks can be very minute and hard to find. If you are considering selling, PLEASE BE CAREFUL. THERE ARE MANY EYES THAT WATCH THIS SITE DILIGENTLY LOOKING FOR PEOPLE JUST LIKE YOU, LOOKING TO LOWBALL BEFORE SOMEONE ELSE GIVES AN HONEST AND FORTHRIGHT APPRAISAL...."YOUR DRUMS ARE JUST OLD LUDWIGS, NOT REALLY WORTH A LOT, I'LL TAKE THEM OFF YOUR HANDS FOR $400.00"....RIGHT.
YOUR DRUMS ARE, BARRING ANY REALLY BAD DAMAGES, WORTH MUCH MORE THAN THAT.
I think I got everything that will get you the best and brightest of our minds to working on it for you.
Have a great week!
Sizes are also invaluable to a determination of value. This appears to be a "Downbeat" kit, they would be Bass~20~tom~12~floor tom~14 (20-12-14 and that floor tom, if it is 14x14, is worth more than it's wieght in platinum) and looks like a Supraphonic snare. Is it a chrome over alloy or brass? Or do you even know?
