Does anyone have a paper tape punch for sale, to suit 1" tape?

Hello
Not sure if you have got sorted
I have a 1" paper tape punch (not sure if it will do Mylar)
It will
punch a tape from rs232
output rs232 from a tape (about 8 configurable options)
copy a tape
I used to use it for cnc machines
It has a 4digit pin code to alter configurations but code is lost
I have also lost the instructions at the moment
I also have a reel or two of paper tape
It will be at most half the price of your example
Stored at Lincoln

Hi,
what make and model is it?

I'm guessing that as it is a combined punch/reader unit it's probably not suitable for Mylar, but anything is possible? It would be good to be wrong, in this case!
(If it's a GNT 4000 series one, that's the type we already have, that cannot do Mylar).

The punch is a Teleport
It is in storage so I will have to visit and take some details for you
I should know by late afternoon
Regards

The punch is a teleport 300 made by Telepro ltd of Dudley (weight approx 8kg)
They were the last uk company to make paper punch/read machines
I read on the internet that GNT took Telepro over so it may have been rebadged as a GNT product later on
I dont have anything that will output serial data (it will read/punch EIA and ASCII) so cant test it (it was fully functional before storage)
It is a stand alone machine that will take a full roll of 1" tape
It has two 25pin "D" connectors at the back - Line and Terminal

This is a GNT one, similar to ours:

From some info I've found, the earliest GNT ones may have been compatible with Mylar, so yours just could be??

A good way forward would be for me to take a picture of the machine and you may be able to identify it
I am not sure how many pictures I can attach
Another way would be try and punch some mylar tape - I have some punched tape to copy
If you have some spare you could post it to me?

Pictures & model number may help?

Testing with tape is not practical; the GNT machines we have can often punch anything from tens to hundreds of feet, or jam possibly 2 - 3 times per full roll of tape.
They punch, but the pins just occasionally snag and do not retract fast enough, causing a misfeed and character loss.

If you need better photos can I send you some by PM
