Yes, essentially. Blockboard is basically pine laminate, like stuff kitchen cabinets might be made of; the original guitar has two layers (top and bottom) and an oak centre section to which the neck, bridge and trem are mounted. The fretboard is also oak, stained black and lacquered. I imagine if BM and dad had access to better materials back in the day, they'd have built it not unlike the Super is. Still today various aspects of the design more than stand up, and ahead of their time when the guitar was completed.
The colour is one of the most difficult things to get right! The original kinda goes from dark red to brown/orange depending on the light. Can't remember what the red dye they used was, the main body of the finish is Rustin's Plastic Coating.
Similarly, I'd like one because of its versatility and the less than usual vibe, not because I'm interested in copping Queen licks (I do like Queen, of course). Fully agree with your view.
There are a few other makers who do good replicas with a range of options, like Dansan (France), Carpinteri (Italy), Loxley (UK) etc. The cost depends the options, but typically the blockboard version costs more because of the labour involved in building the body. From what I seen, people charge around 5k for a blockboard spec instrument; and similar to the Super for an all mahogany one. Dansan also makes a version of the Birch guitar, which would be cool to have as too

Anyway, congrats on the awesome acquisition; play her well and loud :headbang:.
