Original Window frames wanted

I'm trying to locate a set of original Alloy window frames for our Sabre27. Tillew
A previous owner removed the frames and discarded them.They screwed plexiglass sheets to the outside and tried to seal them with mastic. Of course they leak like a sieve and look awful.
I realise the originals will need modification and refurbishment but at least we'll have something to work with. I noticed a set, advertised for sale on BoatsfromUK.com by an owner in Fareham but have not been able to contact them.
Anyone know the whereabouts of a set ?
Regards,
Tom

If you want a decent set of window frames you may have to commission new ones, because any used frames are likely to be U/S, or may not fit your openings (there were some variations). I got mine from the firm trading as Technautic and they have been very satisfactory. The most important stage is the making of accurate cardboard templates of the openings and deciding on the screw/bolt fixing options and positions.
Apologies for this slow response - and Good luck.

There is no point fitting 40 - 50 year old frames even if you can find a set, as they are likely to have lost all their anodising & have corrosion issues.
Technautic made a new set of windows up for our boat 12 years ago & they have been good, now need resealing though.

Thanks for the replies,
Apologies for posting twice as I only saw them now.
Will look at Technautic but still looking for an old set to use as patterns.
I understand your point about using 50 year old windows.
Much has been modified on our boat and I'm trying to reverse engineer everything back to standard before ordering windows.

Best Regards,

Tom
PS
If anyone has a Sabre 27 based in Ireland, please get in touch.

All you need for a pattern is put a hardboard sheet over the window aperture & have someone draw round it. Cut it out & Technautic will make the window frames from that. The most important thing when using interscrews (that these windows do) Is that the grp cabin side is constant thickness, If it varys some screws will bottom out & wont tighten properly. Some grp & filler to build up low areas will be helpful.
Don't under any circumstances fit the new windows with sikaflex as when you have to reseal them you will not get them out without damaging them.
