@RyanOP,
I’m using 700c x 28s, the tyres are Schwalbe Marathons. There isn’t a lot of room but I think I could fit 700c x 32s , but not 38s. The rims are Mavic 3CDs, there’s not a lot of room between the rims and the inner face of the forks for the brake pads, but enough. I dont think you’ll ha a problem with the rims describe earlier in the thread. I attach a close-up picture of the front brakes. You can see I have fitted mudguards - SKS Bluemel hybrid size, and I think I’ll fit 32s underneath them. The brake cable might preclude bigger mudguards.

The BB for the Galaxy is UN55 with 68mm shell width with English threads and a spindle length of 110mm, which suits the triple crankset.
The paint job on the Galaxy is a simple single colour, without metallics or other additives. These would have increased the job cost.
Powder coating is less expensive but may provide less corrosion protection as there’s no primer coat, if the powder coat is damaged. One option would be to get the main colour done in a paint shop then add any other colours (banding) yourself - not something I have any experience of I’m afraid.
I hope you manage to find a local paint shop in Hull. I lived there in 2018-19 but didn’t come across one locally.
