So by now we all know the apprentice sabers are what you see is what you get.
Or are they?
I stopped by the showroom to check out the new designs(very nice by the way, the Bastian is amazing) and test a thought I had the other day.
The pommels in the apprentice sabers unscrew. There are a variety of options on pommels. Why couldn't you add an ASP pommel to an apprentice saber?
Well you can and you can't. To test this I took the pommels off some elite sabers and off of some apprentice sabers. The acolyte has that curved bottom so almost no ASP pommel is going to fit inside. Something else we found out is some pommels have longer threads than others. So while the hilt will receive the pommel, you run out of depth before it's tight. Some other pommels had less threads and they would go tight on other bodies.
Not really sure how useful this is, but I mainly wanted to share because the showroom was so great in helping me answer this question. Instead of saying 'no', he said, "I don't know". When I asked if we could find out, he was more than happy to allow me to play with the parts and find out.
So it's doable but there is a ton of factors to consider and it really turns into a huge MAYBE.
