Some decent info already offered.
For me, the LF outfit looks in reasonable condition for its age.
Closer inspection may well show many small faults due to wear but going on my own experiences with refurbing old kit to a point where they could be used ( albiet just occasionally), I reckon you have a good chance with this kit.
Personally I wouldn’t modify the format . If half plate ,much as the film is not readily available, it can be sourced.
Assuming you have some basic diy skills ( mine are very basic), I would suggest initially a thorough clean possibly involving a dismantle of the camera.
The key word here is patience!
If screws are tight or pieces won’t come apart/ reassemble without force then take a deep breath and reassess the problem even if it means walking away and returning several hours
This actually relates to LF in general even with new kit. If something needs forcing, then something is clearly adrift.
This links you to the last restoration that I did of a 13x18 ( close ish to half plate) outfit kindly given to me by a friend
This thread is pretty much due to the request of @ChrisR who basically asked for a commentary on the rebuild of this french 13x18cm Tailboard bellows camera that i was recently given. ( Original details here: OFFICIAL I HAVE A NEW (FILM RELATED) TOY THREAD!! | Page 276 | Talk Photography...

It works and I’ve had a couple of photos from it but due to its age related fragility, it only gets used very occasionally.
Tag me or pm me if you come up against a particular problem …. I may be able to advise .
