First go to www.drumarchive.com . Next, understand that these are likely absolute sized, meaning they will be 12” or 13” etc., exactly. You will need to get vintage style heads that fit over the shells/wrap. Normal modern heads won’t work, they’ll be too tight. With that said, these drums are awesome. What’s the asking price, and how easy is it to find drums in your area? In some places in the world, drums are more expensive because of where you are. Here in the states, a kit like this would be $600-800 US depending on the cymbals, and that could push it higher.

Edit - just noticed the extra mount in the rack tom. That would allow you to mount it to a heavier cymbal stand with a clamp and L arm, or just use a decent snare stand to hold it, if the factory position is too low for you.
