Sending Seb's to Mayo

[Walt2]

I have noticed a couple of threads that have mentioned sending Sebs to Mayo to have some service performed. What service does Tom do to the Seb?

If you do a quick search in the Gallery you will see some Modifications done to a Sebbie, Pretty cool I might add. Not sure if he would be taking orders for modifications with his back log though
