Tone arm holes do not line up - best way to attach TT?

This is the Hanss T-30 HANSS ACOUSTICS T-30 (hanss-acoustics.com). From a casual view, your Reed 3P 12" tonearm is probably not going to fit on that turntable. Each turntable has allowable tonearm lengths that will work. Send Hanss and e-mail and ask them what is the longest tonearm pivot to spindle that will fit. If what they tell indicates that your Reed 3P 12" is not going to fit you have some options:

-return the Reed and get one that is a shorter length.
-have a plate machined to cantilever from the existing tonearm base to allow mounting the 12" Reed.
-buy a separate tonearm pod to allow using the Reed 12".

Do you have the Reed 3P manual?  If not - download here -  Bedienungsanleitung-Tonarm-Reed-3P.pdf (bohne-audio.com) and follow directions accordingly.  

When you say the turntable can handle a 12" tonearm - does it have an adjustable armboard - each tonearm has a specific mounting pattern.  

For the tonearm to fit, the pivot to spindle distance must be set to a distance of  295.6mm (roundup to 296mm).  Refer to the above manual to determine the pivot point - Figure 5 Item 1.  Make sure you have all adjustments initially set as specified in the manual - including Anti-Skate; too little of which may cause the tonearm to fly to the spindle.  

@mcmanus,

Are you sure you have a 12" arm???  A quick verification it to measure from the tonearm pivot to the end of the headshell - it should be very close to 12".  The next available size from Reed Reed 3P - Reed tonearms is a 10.5" - this arm is about 2" difference.  One item to be careful is that there is a difference between Mounting distance (which is likely what the template shows) and the Pivot to spindle distance which I addressed above.
