Qldspitty & vacb
Thank you both very much for that information. My elevator control link would appear to be .5″ too low. Fortunately, i have not fixed it in place so no problem to move it.

Is it frame 20 (after portion) 30027 sht.102G or 2063G OR 30027 SHT.22G or is it non of these?

Hi Thank you guys for your comments. Much appreciated. The gun button is the only original item on it. The yolk bolt was made from a original drawing so was very useful as a datum point. I have a small collection of G45 cameras. I can connect the column to a air supply and operate the camera via the gun button or the camera button. I also made the 5D534 gun button holder that is operated by the pneumatics. Just need the 8 Brownings now!!

I just go with the flow!

I have made the column from top to bottom myself, apart from the spade grip. i bought a repro, one of the many that are sold as spitfire grips and “converted” it myself to spitfire type. As a matter of interest, what is the length of your column tube?
I can pm you some photo`s if you want to see it?

Thanks vacb.
It would be unlikely for them to go back. It would be like them saying “well, we got that improvement wrong”.

Mmmm.. What we need is someone with a Mk1 column and someone with a Mkv column to go and measure them for us!.. Now, who do we know who has got these????

Your point about the chain guard is the reason i would like to know because, at some great expense, i am going to have one made!!

Yes makes me think that perhaps they did vary between types! I also wonder if they could have just made a mistake? After all, on the drawing they shopw it as drawing No. 30033 – 21 Surely this No. is for the R/H chain guard?..
