Need a mast for Oyster SJ35

I am looking for a second hand mast for Oyster SJ35 with following specifications:

I = 40.23
J = 11.84
P = 42.59
E = 16.06

The Bury is 5.6"

The designed section lengths on the double spreader jumper strut rig are as follows:

Height from datum (deck) in mm

to vang tang( bottom ) = 180
to goosneck (top) = 1206
to lower shroud tangs = 4154
to lower spreader brkt = 4356
to check stay tang = 6550
to spinn sheave box = 7000
to intermediate shroud tang = 7560
to upper spreader brkt = 7787
to jumper tang = 9400
to cap shroud tang = 11281
to haliard exit box = 11436
to forestay tang = 11626
to runner tang (and jumper brkt) = 11715
to haliard exit box = 12050
to haliard exit box = 12300
to jumper tang = 13730
masthead = 14016

Spreaders raked aft 5 deg.

lower spreader 900 ml length (brkt centre to shroud)
upper spreader 660 ml length (brkt centre to shroud)

Cross sectional dimensions:
The mast is: 138/95 .
It would appear that the taper takes place over the final 2700
The boom is 150/105

In addition this mast is keel stepped with 6 feet of it inside cabin, therefore total lengths required 15816 mm or 51.9 ft

Would anyone be able to help me finding a mast for this boat.

Thanks and best regards

Petar
