This was the last show before the Second World War and was held between 16th and 19th May. Again the firm requested a 20ft. square space, which they were allocated on the east side of Monument Road, towards Northern Road. Again they had a corner space fronting both Monument Road and the entrance into the east marquee. Their exhibition stand contained the same products as the previous three years and the accompanying show cards were essentially duplicates of previous years.
There was some discussion as to whether they should reduce the price of the show house, which was the same one displayed last year and in the end they decided against any reduction. This strategy may have worked because they sold it to Mr. P.T. Lovely of Kings Leigh, No. 43, Westmoreland Road, Bromley, Kent. The firm had in October 1938 quoted for a 20ft. by 11ft. span-roof carnation house for Mr. Lovely. An opportunity passed to Messenger’s by Messrs. G.H. Warne, a general builder, with whom Messenger’s had worked with in the past. They were up against several other horticultural suppliers including Mackenzie and Moncur and Weeks. The firm quoted £75 for the structure with wrought iron stages and heating apparatus (including No. 24 Quorn boiler) and £74 for the associated brickwork (for which Mr. Warne quoted £62 10s,the firm having added 10% for themselves and one or two other items). However, Mr. Lovely but decided that the estimates were too expensive. Subsequently he called into the stand on the first day to discuss his quote and was so taken with the show house that he sent his gardener, Mr. Vaughan, to look at it a day or so later. The firm arranged for someone from the London office to visit Mr. Lovely on the morning of Saturday 20th, the day after the show completed. A quote and brickwork plan was sent out on Monday 22nd May and Mr. Lovely accepted prior to 27th. The quote was for a total of £102 17s. 6d., which was considerably more than was quoted the previous October. The quote included the 20ft. by 10ft. show house, priced at £70, wrought iron stages at £14 and heating apparatus, with No. 2 Loughborough boiler for £18 17s. 6d. Whilst the brickwork plan was sent at the same time as the quote, Mr. Lovely took responsibility for employing his own builder to complete the brick foundations. The house was sent directly from the showground on 23rd May, ready to be erected, once the foundations were complete and the stages and heating apparatus delivered. The brickwork was completed by 1st June, the stages and heating apparatus left the factory on Monday 6th June and delivered on Wednesday 8th. The structure, stages and heating were all installed and working well before the 28th June.
