Default 110 mm rear dropout spacing

Last night I picked up a 1955 Raleigh Lenton Grand Prix frame for
$10. It has straight gauge 531 tubing. Very nice.

However, the rear dropout spacing is 110 mm. So what can I do with
that?

I'm assuming that I would need to take it to a frame builder in order
to spread it even to 120 mm, let alone 126 or 130. I don't see any
110 mm rear hubs out there (plus I already have two fixed gears).

Any suggestions?

Older track bikes used 110mm spacing in the rear. Since you already
have two fixed gears, I'll suggest a single speed instead. Might be
able to reduce the spacing on a track hub from 120 to 110.

Get a BMX cassette hub (Chris King are nice...), many of which have
enough width of spline to take 3 sprockets at 10-speed spacing, and
make yourself a groovy modern 3-speed derailleur bike! A 3-speed would
even be period correct for 1955 :-)

Sturmey AW 3 speed hubs are 110 OLN, so that would be another option.
Expect to pay up to $50 for a second hand unit in good condition.

All BMX rear hubs have 110mm spacing. Many of them have 3/8" (9.5mm)
rear axles. There are "flip flop" variants that have a 1-3/8"
freewheel thread on one side (minimum 15t single freewheel) and a 30mm
freewheel thread on the other side (minimum 13t). They are commonly
available in 28, 36, and 48 hole drillings.

Sturmey Archer and other three-speed hubs have spacings of less than
120mm, but usually more than 110mm. Sachs Pentasport/SRAM P5 five-
speed hubs also have versions with sub-120mm spacing.
