BTW I wanted gears for the old Specialized Hardrock frame I got hold of, but decided that 3 were enough so built a Sturmey Archer 3spd hub into the back wheel, came to £20 with the cable, toggle chain and a used trigger shifter and works perfectly. Had to cold set the rear end to 120mm.

Left field suggestion:
Coaster brake rear hub, so rear brake, hub and freewheel sorted, no cables to the rear and you can fit any rim size to it, this is the recommended one: https://www.ebay.co.uk/itm/NEW-Velosteel-Singlespeed-Coaster-Brake-Hub-Classic-European-simplicity/200978518746?hash=item2ecb40d2da:m:mlyJbZpeVyztIClHH3SmEKQ
Now you only need to buy some spokes, e.g. https://www.jejamescycles.com/halo-ed-plain-gauge-spokes-14g-black-with-nipples.html?gclid=EAIaIQobChMIzoGe57DI2wIVy7XtCh2rJACeEAYYAiABEgKQKvD_BwE spoke washers, 2 per spoke, as the steel hub flanges are very thin https://www.jejamescycles.com/sapim-spoke-washers-pcg2836.html and the rest, wheels, front brake and lever etc can be scavenged from dead MTBs on freecycle, the tip or your mates' back sheds or gardens, or off those half robbed abandoned bikes you find chained to railings lamp posts.EDIT: you're already looking at coaster brake hubs, duh!

9.4kg/20.7lb without mudguards or lights. Think I will swap out that front dynamo hub with a non dynamo Deore LX I have to bring weight down by 280g. Don't really need anything more than a couple of blinkies on my short commute on lit streets, but definitely do need the mudguards here in deepest Cornwall and also lowish gearing for an old bloke coping with the moderately hilly terrain. That is a 38t chainring with a 16t freewheel, giving 64" gear with the 32mm tyres. I took it on a shakedown run and it does accelerate and roll well, and runs very quiet and smooth. The pedals are garbage from the back of the shed, but will be replaced with some Humpert 608s ASAP

Nope its 700c, with enough clearance for mudguards and my preferred 32mm tyres, plus v-brake bosses which I prefer over discs (and 32mm tyres won't squeeze into caliper brakes). Also weight is reasonable for the clearance, the v-brake bosses add to the weight but OTOH mini v-brakes are pretty light.

Frame looked like this when purchased:
I paid £45 including postage, but sold the 1.2Kg steel forks on getting a fiver back. -
Won't upload for some reason, so using Flickr to host again:

Mock up of possible final positioning, note bell:
The Specialized has the same short type horizontal dropouts. Chain tension is fine right now but only got about 1/4" of adjustment available, so eventually will need either a half link or I can just buy a new chain (1/8" KMC B1 chains are dirt cheap and long lasting anyway). Still much better than vertical dropouts.
Dibs on that Sturmey X-FDD drum brake/dynamo if you decide to sell it, PM sent....
