I have several three piece razors and they all stay matched head to handle. The only exception is my Stahly. While the oversized vibrating handle works, I find it too bulky for my liking, and the vibrating feature adds nothing to the shave. I love the head of the Stahly, so when it comes around in rotation I'll put it on a Fat Handle Tech handle or a NEW handle for the duration of the shave, then it goes back on the correct handle.
Ah, Ok. But, I'm not sure if the cap and base plate on this razor are actually matched. The base is a D2. But, I have no idea if this is the original cap.
Whenever a new three piece enters my den I examine the top cap to determine its Frankenpotential. I agree with TobyC, swapping handles is just swapping handles it's not Frankenrazoring. My Pearl OC and R41 I swap caps on.
Yes, as @PanChango said, I carved it from wood to simulate a fatboy. It is not adjustable, it just looks that way.
My last creature ... https://theshaveden.com/forums/posts/1911997/ FrankenRazor Ghost Trotter (Spectre CC / Yaqi Globe Trotter) Super light, super efficient. Head is a little aggressive, and very light. Balanced just few grams on the resin handle. Total 30g, 13 / 17. Love the color contrast. Looks like something as vintage.
