As I get older my inside leg seems to be getting shorter, is there a way to drop the seat down by about an inch at the front. 21inch front wheel and 19 inch back wheel.

I've not seen this done but maybe you could alter the fixing at the front of the seat to lower it a little. e.g. Possibly slot the holes or modify the bracket to allow the seat to come back a little and down.
You might also be able to remove some foam from the seat to lose some height.

I reduced the height of the squab in the extended seat to that of a standard one you could do the same with a standard one a professional upholsterer will do a good job mine cost £20
I have not found the twin a problem but on The Comet suggest I spent some time on the problem fitting folding footrests buy them from spares company or make them from LH footrest hangers and (say) Meriden Triumph pillion footrests.
Lowering the front bracket is less problematical if seat is fully spring but there is not a lot of room to tank fixings
Radical seat lowering can lead to cramp in riders legs on a Comet (ask my wife!)
Finally 18 inch wheels and boots with thicker soles or suspension adjustment may be needed.Go slowly with mods it's suprisng what even half an inch can do

I have the same problem and keep looking at a swoopy BSA twin seat with wrecked upholstery I have doing nothing, I could alter that to fit losing another 1.5", alright the tooltray would have to go.
The next problem I can see is the footrests (twin) already feel too high with my thinned down extended seat for my stiffening joints.

Hi Vibrac, thanks for the reply, this is an extended seat from Neal Videan, i could reduce the height but not only are my legs shorter but my backside bonier, not to sure of a thinner seat.

Hi Eric, the rear has the Thornton set up, thanks for the reply.

P.S.
I also meant to say that whenever you alter the seat position check that there is still clearance between the mudguard and the underside of the seat. This is less likely if you are just lowering the front a little.
My setup is fully floating with an AVO monoshock suspension unit. I also have the longer Spares Co. seat. I had to turn over the lifting handle to move it rearwards to stop it hitting the rear of the seat.
