Contacted Littlejohn Graphics and advised it is most probably the Hunter Penrose / Littlejohn No2 Etching Press as shown on the promotional  info sheet of the time and this is how I remember it when in use  

Their estimated value in good condition £1000 - £1300 with bed

Information sheet states :-   Steel plate side frames

Solid steel precision ground top roller 3ins diameter

Single geared solid steel bottom roller 3ins diameter

Precision ball bearings to both rollers

18ins plastic coated operating wheel

Net weight approx 67.5 kg

Some minor pitting on rollers (photo 6 ) not deep which should not interfere with function due to blankets only with aesthetics

There is no bed supplied but bed size was/is  16ins x 24ins x 1/4ins thick

Dismantled by engineer & all parts retained since when has been stored unused (indoors) as no workshop space available

Was in good working order

Sold as seen and would have to be collected as such -  whilst putting together is straight forward & requires hand tools some knowledge would be advantageous

Collection only  -  based in Bingley,  West Yorkshire
