Thanks for being curious,
@henryjurstin13, and I apologize off-topic-ism to all others.
#5 is a Linus Paganini, #6 is a Linus Custom Thinline ('Honey Amber'). And #4 is a Linus Red Scorpion.
Linus is based at Lake Constance in the Austrian city of Bregenz. Peter Steinacher is the founder and luthier of the one-man-guitar company. In 2013 I asked him to build me a guitar. I was impressed by the PRS NS15, but didn't want either a FR or a Bigsby (nowadays I regret being reluctant regarding the Bigsby at that time). Anyways. It is a unique guitar. Staying in chronical order: 2020 I was little bit bored off-duty whilst touring Afghanistan for more than six months, and sneaked on Peter's homepage. Over a long period of time I was literally a Tele hater.
The purchase of a Revered Gristlemaster Greg Koch Signature relieved my hatred. Peter made two comparable Gretsch inspired T-Styles ('Green Mamba' and 'The Benz'). The more often I looked at those, the more my GAS increased.
I asked Peter, if he would build me a second custom made guitar. My specs turned into reality as the Red Scorpion.
#5: I spent a months in the beginning of 2022 in vicinity of Lake Constance, where our military EOD school is located. Periodicly we need to attend to a refresher training to keep the EOD/IEDD operator qualification vital. I took the opportunity to visit Peter on one weekend.
He offered me a tour through his wood shop. In a stand rest three of those guitars under construction. In general his approach is to make custom ordered instruments, but those type of instrument is a series of max. 20 instruments. His interpretation of a violin guitar. Strativari is Strat-type (with Strat scale), Paganini is a LP-type (with LP scale), and he built bass guitars.
Okay. I knew of this violins, but I was actually not a fan of the design. Prior the time in his wood shop, we chatted in his office, I was allowed to play all of his private guitars. And one of it was his Strativari. It mitigated my distance against this type of design. One of the three Paganinis under construction had as an inlay a tree of life. That reminded me on a christmas present of my mother in the year her husband/my father passed away. Not directly, but 24 hrs later I asked Peter, if he would complete it for me. He highly appreciated my wish. A few months later it was shipped.
