johny Posted January 2, 2022 Report Share Posted January 2, 2022 If anyones interested and in the Norfolk area I think this non OD gearbox is for an 1850 and not as the seller (no relation) indicates for a Spitfire. I contacted him ages ago and, although he cant find the serial number, the input shaft length seems correct for fitting to a Vitesse or GT6. The box would need modifying but should have the bigger synchros and mainshaft tip plus later cut gears so I would be interested myself but its too far and anyway I already have too many spares... https://www.ebay.co.uk/itm/154775942800 Link to comment Share on other sites More sharing options...
thescrapman Posted January 2, 2022 Report Share Posted January 2, 2022 Not Triumph. Look at rear mount and speedo drive, neither look right. Marina? Link to comment Share on other sites More sharing options...
Colin Lindsay Posted January 3, 2022 Report Share Posted January 3, 2022 Probably MG, maybe Midget. Link to comment Share on other sites More sharing options...
johny Posted January 3, 2022 Author Report Share Posted January 3, 2022 I think the Midget will have the same input shaft length as a Spitfire and this one is longer but not as long as a TR7 unit. Scrapman could be right as maybe the Marina unit matched the 1850 unit in size but unfortunately not in ratios. This might explain why the seller cant find the serial number although I dont think he's looked very hard as it could be under that paint...

thescrapman Posted January 3, 2022 Report Share Posted January 3, 2022 The part number on the rear extension translates as MG Midget and Spitfire Mk4 1500 (US version?) So perhaps it is. Had forgotten about TR7 4-speed. The paint colour is that used by a major reconditioning company many years ago, and they painted everything. I have one still in its plastic wrapper.

If thats been painted over , or missing i would stear clear! Either its badly looked after or dodgy provenance. cor dear I reckon he would take 30 quid for it so not too much of a gamble - you could end up with the best standard gear set available for GT6/Vitesse and theres not many of those left! Guess the only way to really know what it is would be to count the first gear turns ratio... Link to comment Share on other sites More sharing options...
johny Posted January 5, 2022 Author Report Share Posted January 5, 2022 I see it went so was it someone on here that took the gamble? Link to comment Share on other sites More sharing options...
